Will Cameras Replace Sideview Mirrors On Cars In 2018? 496

cartechboy (2660665) writes "Just the other day we read about how the Department of Transportation will require all manufacturers to include rearview cameras on all new cars produced after May 1, 2018. But there's something else auto manufacturers are pushing for, the ability to replace sideview mirrors with cameras in 2018. Tesla in particular is pushing for this to happen as traditional mirrors are bulky, and not very aerodynamic. That lump of plastic can cause surprising amounts of drag on an otherwise smooth car body. Camera units are much smaller and can be made streamlined, or even mounted nearly flush with the body, thus reducing aerodynamic drag. The idea has been around since the 1990s, and many concept cars have used cameras instead of sideview mirrors for years. But how will NHTSA respond? Is it finally time to ditch the sideview mirror?"

    When you see the cost of replacing a mirror, it'd be cheaper to have a camera and a 7" screen inside.
    On the other hand, night vision would suffer from having a screen on.

    And I know more than one person who has saved their cars' doors by having the mirror remind them how close they really were to that post...

      It won't be cheaper because everyone will have their own vehicles-specific mounts, adapters and enclosures which they will sell at ridiculous rates like every other car part.

    • Unless the cameras have night vision too... like some expensive cars already do. They have a front facing infrared camera and screen on the dashboard. It can pick out heat signatures behind objects like bushes, highlight human shared and temperature objects and calculate their speed and direction to warn you if they're going to cross your path.

      If a window breaks, you can still see through it. If a monitor in your tank breaks?

      I'm totally with Tesla that it should be a legal option, but it shouldn't be a requirement to go digital with side view. On one hand, you have the drag...on the other hand, the classic mirrors are less prone to ceasing to function effectively. (smudging/moisture/frost is also a concern, which often renders my rear camera useless -- easily fixed with classic mirrors, and driver's side can wiped off while driving)

        I live in Copenhagen and drive a bike, I think replacing sideview mirrors with cameras is a horrible idea. If someone is driving around with a broken mirror, I can tell from a long distance, and I will know to be careful around that driver - if he breaks his monitor or camera and don't get it replaced, I will have zero "heads up" about his lack of information.

          How can you spot cars that are long-overdue on having their brakes serviced so that you can be careful around them as well? This is a terrible reason for requiring mirrors on a car.

    Even if you put the screen up by the window, with a mirror you can always move your head a bit to get a bit more visual context. With a camera and screen, that doesn't work. Unless they also put in head tracking, or use a 3d screen.

        This is exactly what I was thinking. A mirror provides both eyes with information, allowing you to gauge depth easily. Depth sensors etc could be used to provide some additional cues, but it is tough to be replace the usefulness of true binocular vision. While my backup camera is great, it definitely is not a replacement for my rearview mirror for this reason.

      The only reason you have to move your head around with a side mirror is because they are placed very close to where your peripheral vision ends. Consequently, if you're sitting facing forward, for a mirror to show the region between where the rearview mirror's view ends (almost straight back) to where your peripheral vision picks up (almost straight to the side), it has to have a very large field of view.

      With a camera, you have the option of mounting it at the front corners of the car instead of by the driver, The display can still be by the driver, but the camera can be way in front. It can then show the same area using a much smaller field of view. The blind spot will still be there, but it'll be pushed out to 2-3 lanes away, making it irrelevant.

        I imagine he was speaking of being able to move your head a little more and check the blind spot on that side.

        The blind spot will still be there, but it'll be pushed out to 2-3 lanes away, making it irrelevant.

        Except when you're changing lanes. And we'll see if the blind spot is still there or not. A lot of cars taper in front, meaning there isn't a mount point for such a camera.

        • Put a camera where the sideview mirrors currently are. This gives you the field of view of the outside edge of the mirror, rather than mostly in the middle. Given the right alignment, it will see everything you can by moving your head around. Put two cameras there, and you can even put a "fish-eye mirror" view in part of the field of view, and have more perspective than you'd ever normally have.

          Another option is to put the cameras on the roof, near where the windshield meets the roof. This could be done

          No, almost no cars taper in the front. There isn't a modern car that exposes the tires to the air, so at "worst" the camera could be in front of the front tires, which is a good distance forward of the "standard" placement for most cars.

    So why do I need a camera? This is a classic case of over-engineering a simple, solved problem. Rear and side view mirrors have an extremely low failure rate, and require no power.

    • Rear view mirrors don't let you see the space obscured by the trunk, and side view mirrors cost $$$ due to aerodynamic drag.

      I love the idea because I think I'll get a wider field of view and better nighttime rear vision.

    • Back when the aptera was a possibility, they removed the mirrors in favor of camera for the aerodynamic gains. (Aptera was a very aerodynamic car so the gains were real). Unfortunately, state laws didn't allow it everywhere, so they had to put them back on.

      Also, mirrors aren't that simple. Even in many low end cars, they have electronics to move them around in the meantime for the driver and I'm it can break. Mirror themselves often are poorly made and lose their finish (see this on vans and the like).

    I always wondered why aircraft don't have embedded cameras all around. One to observe the landing gear, one pointed at the tail rudder, one for each engine, one for the ailerons/flaps etc. No more guessing what is going on based on instrumentation and sending a crewman to look out the window to see if he can spot the problem. Easier to detect icing, snow load on the wing while on the runway, etc.

      Airliners do have external cameras, mainly for taxiing (on some airliners the pilot is seated forward of the nose wheel and if you're in a tight spot it is very useful to actually be able to see under the plane and be able to just barely cut corners near the edges of the taxiways. Having cameras pointed at control surfaces isn't actually a bad idea, but they do have servos on them and their positions can be displayed in the cockpit.

  • In a tight economy, side cameras will only sell if they are a. manditory on all new models, or. b. not marked up at the same exorbitant rate as side mirrors. If the industry cintents itself with a replacement price that's not much more than for conventional mirrors, this could work, but what I expect is a scenario more like this.

    1. Car companies decide that the lower profile possible means fewer side viewers will be hit in accidents, so they will see fewer replacements.

      Actually, one of the reasons for having cameras is that they can boost fuel economy. With CAFE requirements that means that manufacturers can sell more SUVs and stay under the limits. So, there is plenty of incentive to put reasonably-priced cameras on cars, if not make them standard.

    The advantage of side view mirrors from a situational awareness perspective is that you can check the entire side of your car from front to back very quickly because the whole view is there. Blind spot indicators solve the problem of blind spots (mostly..). Side view mirrors may take away from aerodynamics but they're a very convenient place to look.

    A camera image could be nice (night vision, variable view angle, etc), but it seems a downgrade from a safety perspective to use a center console display because it causes you to look away from the side of the car.

    Maybe they'd mount mirror-size displays in the dash against the doors? Sounds kind of expensive for any usable resolution and brightness and maybe even distracting, especially at night. Perhaps the displays could have a secondary function or overlay (distance to largest and maybe bonus points for being hackable to display some other display.

    Displaying a heads-up type display on the windshield? Some kind of perspective-corrected or floats-outside-the-car-like-a-real-mirror image on the side windows (useless if the windows are rolled down, though).

    A rearview mirror option might not be a bad idea because it would then be a complete "behind you" image, but how big could it be without making the rearview mirror into a head-injury risk?
