This should hardly be a surprise to anybody who isn't drinking the kool-aid. The rules of the road would be hard enough to reliably implement let alone the dynamic conditions that occur on them - break downs, floods, road works, lights that are out, diversions, blind corners, cars backing out, emergency vehicles, pedestrians crossing, flying debris, cops directing traffic etc.

Maybe if there is an alert, attentive human to override the dumbass car then perhaps this would be okay but Musk has a perpetual problem of lying about the capabilities of his car that actively encourages them NOT to pay attention. And when they crash Tesla bleats its not their fault even though they were not enforcing the driver's attention. And aside from that, Tesla clearly imagines a day that their cars will be driving around without a driver when it is nowhere close to being that reliable.
