How Would Driver-less Cars Change Motoring? 648
Hugh Pickens writes "BBC reports that as Nevada licenses Google to test its prototype driver-less car on public roads, futurists are postulating what a world of driver-less would cars look like. First, accidents would go down. 'Your automated car isn't sitting around getting distracted, making a phone call, looking at something it shouldn't be looking at or simply not keeping track of things,' says Danny Sullivan. Google's car adheres strictly to the speed limit and follows the rules of the road. 'It doesn't speed, it doesn't cut you off, it doesn't tailgate,' says Tom Jacobs, a spokesman for the Nevada Department of Motor Vehicles. Driver-less cars would mean a more productive commute. 'If you truly trust the intelligence of the vehicle, then you get in the vehicle and you do our work while you're traveling,' says engineer Lynne Irwin. They would mean fewer traffic jams. 'Congestion would be something you could tell your grandchildren about, once upon a time.' Driver-less cars could extend car ownership to some groups of people previously unable to own a car, including elderly drivers who feel uncomfortable getting behind the wheel at night, whose eyesight has weakened or whose reaction time has slowed."
Another reader points out an article suggesting autonomous cars could eventually spell the end of auto insurance.

Well, right, you hit the nail on the head with that last part. As long as there are manual overrides -- and there will *always* be manual overrides -- there will be people who use it to game the system. In fact, I wouldn't be surprised if human drivers actually drive more recklessly because they know that the automated vehicles around them will always yield, always be aware of the vehicles around them, and always avoid collisions. This would provide a huge disincentive for people to use automated vehicles, especially in rush hour traffic where they're needed most, because the automated vehicle wouldn't be aggressive enough, and the manual driver wouldn't be hindered by the same set of programmed restrictions as the automated vehicle. If people see a measurable advantage to driving manually, they will continue to do it.
In light of that, I can only think of one way this will work long-term and large-scale, and that's by making manual driving illegal on public roads except in emergency situations. (The penalties for noncompliance could be much more stringent than they are for reckless driving today, because intent would be a given.) I'm afraid anything less will only encourage people to drive like even bigger assholes than they already do.

Add on ancillary features like monitoring your adherence to speed limits, the crime rate where your car is parked for long periods, and the time between maintenance checkups, and the insurer has a nice way to identify their safest clients to offer a well-advertised discount, and their riskiest drivers to raise their premiums.

Ah, but most of the problem with 'rush hour' is that the majority of those cars are only carrying one, or maybe two passengers.
A city-wide routing system should be able to plan a route to pick up a dozen or so people who are starting from / traveling to similar places, and get it all done in one vehicle. To prevent it from being just like a bus ride, subway or shared taxi (congested, noisy, kids beside you blaring their youtube videos, people breathing down the back of your neck, etc.), all the designers would have to do is build cars/vans that had segregated one / two / four person compartments, each with it's own external door (think a stretch limo with several doors on each side and a wall down the middle). Then you just swipe your pass/phone/whatever to confirm it's you, get in and relax, ignoring any other pickups or drop-offs until you get to your stop (car could 'bing' you at your stop, in case you dozed off).
Higher end services could even stock a mini-bar in each compartment, for those who want to unwind a bit before dinner. :o) Or, better yet, you could have the car 'pick up' dinner for you before coming to pick you up (just send it to your local restaurant and have them place it in the compartment reserved for you).

Well, they were not comparing it to public transportation. They were comparing driverLESS cars to cars with drivers. If they were comparing it to public transportation, they would have mentioned things like, you can leave directly from your house, you can change your mind mid trip, you can leave whenever you like and not be tied to a bus schedule, there are no transfers, you can make impulse stops at stores and restaurants, you car does not have "hours of operation", and many many other advantages to driving your own vehicle as opposed to public transportation.
Eventually, though, this system will be much like public transportation, except with the advantages I listed above. There will be routes designated for driverless travel. For example, the freeways may have a driverless lane, much like an HOV lane, whereas you may have to man the steering wheel while in neighborhoods. Efficiency will be greatly improved with constant speeds and drafting. Maybe not to the level of public transportation, but certainly better than now. It may even be possible to put rails on these roads to power electric vehicles, which would surpass public transportation (it would be more efficient as your vehicle does not have to stop and every single stop and then start back up again). The way I see it, driverless cars could be better than public transportation in every way, maybe with the exception of efficiency.
In the end, our cars will be more like a small bedroom, living room or office. We'll have a couch and a TV/monitor or a desk with a computer or whatever you want. There will be no steering wheel, gas pedal, or designated seats. If the system works well enough, we won't even need seat belts. Every car will be like a limo without a driver.

America has many well designed cities. And many poorly designed cities. However, if all cars were converted to driverless, then the increased efficiency may be such that you could have far fewer roads because a road could handle that many more cars without becoming congested - especially with some sort of inter-vehicle communication protocol. You could have cars traveling 100 mph almost bumper to bumper on highways that are currently at 55mph. This would allow you to have more roads designated cars-only to avoid many of the pitfalls of mixed traffic. The next step will likely be driverless cars with the option to switch to manual (think Demolition Man) for areas that are not driverless-friendly.

It may also mean some roads would get redesigned to better accommodate automation. I somehow doubt the plethora of signs about hidden intersections, white and yellow dotted lines, reflective signs etc existed in the era of horse and buggy, or even in the early era of cars.
The challenge is getting automated cars to the point that such modifications become worthwhile.

A good point. When playing Sim City, "fun" designs are nice for small towns (only practical at all in SimCity 4) or very small neighborhoods but they completely lack scalability. I don't think the roads add a personal touch half so much as the buildings, businesses and homes alongside them.

The most navigable cities I've driven through have a layout where most of the city is a typical grid (often North/South/East/West) but have a few major avenues going at a 45 degree angle (NE/SW and NW/SE) just to help cut across the grid. Most of the cities here also have one expressway looping around the outside of the city and another one cutting through the heart of it - between them, you can get fairly close to your destination pretty fast.

To a large extent this is just because they have been planned, whereas many older cities in Europe and Asia were built up well before modern city planning. There are other factors as well- cities that are planned well become less well-planned as time goes on. You see this in Europe with some of the old Roman cities. Also, when one didn't have cars and trucks, smaller alleyways weren't a problem, whereas many expanded American cities happened just as cars were showing up (remember the frontier in the US doesn't close until the 1890s). There's also just a long tradition in the US of careful planning, that's dates back to the very early settlements. New York was gridded out when much of the city was still wilderness, and that started a general precedent. There are some cities that aren't as carefully gridded (such as Boston) but many cities modeled themselves in a similar way to New York. Also, in much of the US land was pretty cheap. Gridding with big roads takes a lot of land up- when you have the room it is easier to do it.

When London, Beijing, Cairo, and most other ancient cities were first laid out, their main roads connected little groups of buildings, in whatever way was convenient at the time. Maps didn't exist commonly, let alone a postal service, so the only important measure of efficiency was transit time on foot. With nothing else around them, those roads could be made straight, bending only around geographic features. This is clearly evident in rural Africa, where the roads between farms are generally straight, but run at odd angles.
Newer cities (including all the ones in America, which were all built in the last 500 years) were designed for people and postmen. Cities were expected to have a high population density, so their roads are designed to make the biggest buildings possible: rectangles. Their addressing was designed for efficiency, to the extent where cities like Salt Lake City, Utah have primarily numbered streets, with names being used only for main routes. There are still many odd angles, but they're generally old major routes that the city has grown around. Even landscape is getting ignored in favor of efficiency, with roads often stopping at a river's edge and continuing on the other side.
All of this means that outside America, Google Car has little use.
Conveniently, modern routing algorithms have absolutely no problem with any of these designs. Modern algorithms treat the city as a graph of intersections, knowing what intersections connect to what other intersections, how far apart they are (by time, distance, and even traffic density) and knowing what building numbers are between what intersections. The actual placement of those intersections doesn't matter when planning a route, but only when actually making a map for humans to follow.
In fact they would be fatal to others on the road.
As I'm sure has been pointed out by others by now, this is ridiculous. An automated car can be just as sensitive as any human-driven car, and often moreso. An automated car has cameras and laser sensors on it, that can poll thousands of points each second to construct a map of the world. Unlike humans, the sensors don't suffer from blindness, distraction, or optical illusions. If there's an elephant in front of the car, the car will know that there's an elephant-shaped object in front of it, and it will recognize the turning lights on its ass. the moment they come on.
Also unlike humans, an automated car is capable of communicating with other automated cars on the road. Despite what the summary says, they can tailgate, and they can cut each other off. The difference is that they'll be in constant communication at the time, so that if one car needs to stop, it will give plenty of notice to other cars, who will all apply their brakes at the same time at different strengths, so they will decelerate in unison. Cars traveling a half-meter apart on the highway will stop a half-meter apart, too.
With this communication, it's fully possible for a car to see around corners. Not only are there sonar sensors capable of making a decent guess as to what's approaching, but there are also projects to make stationary sensors, to be placed near intersections. These would watch for regular old dumb cars (and people, cats, dogs, and elephants, too), monitor their position and velocity, and send reports to automated cars in the area, which can then make fully-informed decisions about what to do.
I doubt Google has thought of this and they will be in for a big surprise when nobody but Americans can use them.
I can assure you that Google has thought of this. That's why Google Maps works for routes outside the United States, and why self-driving robots have been a major field of research for a few decades.

Instead of having to make all those mistakes that you must accept forever, (because the cost to undo them is too high) cities developed later tend to be developed better. Learning from the mistakes of the past.

Self-driving cars not only use a variety of sensors to assess the environment, but also have systems based on algorithms like SLAM (Simultaneous localization and mapping) to help them position themselves relative to the environment, and position landmarks relative to them. All kinds of sensors are involved, but especially laser range sensors which would prevent the kind of problems caused by GPS returning invalid results (the car won't just drive into a wall, it will avoid the wall and reduce the belief associated with the current location). GPS is just an extra sensor, not a bunch of set-in-stone instructions.
They don't hit the pot hole because there are computer vision systems that, along with the range sensors, can make a reliable guess at whether that is a pot hole or not, and avoid it. Speed would be irrelevant as the computer can react faster, and more accurately than a human driver could.
When it comes to this kinds of algorithms, sometimes they are *too* efficient, and you have to route around that: a good example is going around walls, in which the car might decide to hug the wall and take a turn very, very close to the corner - but this is not optimal as a) the driver would probably freak out b) Movement and location sensors are not perfect, you always have to consider actuator and sensor noise. So, the algorithms are complemented by a penalty for getting too close to objects, even if it wouldn't cause a collision.
I hope that helps paint a broad picture of the system to make a bit more understandable.

Well theoretically they could all stop at the same time, more-or-less. The front car detects an obstacle in the road, and the message propagates back over the mesh network between cars.
If you were really clever what you'd do is make the line of cars slow down, then only speed up again once they'd increased their gaps a bit. This would absorb the sudden "bump" in traffic flow and prevent that "what the hell are we slowing right down for, there's absolutely nothing!" thing happening.

Right now, you're supposed to maintain sufficient distance from the cars around you that if something happens to them, you have time to react. Cars should never be moving at 180 KPH within centimeters of each other for exactly the reason you state.
