Something like 93% of all crashes are driver error. If we take the driver out of the equation that leaves us 7% of the collisions we have now. Assume the cars fail 2x more because they are more complex, that's still 86% fewer crashes.
How dare you throw facts and statistics into this conversation!
Most of the problems on our roads will be solved when the human is removed from the equation. Yes, you'll still have to be there for times when the computer might be unable to handle a particular task, but the absence of idiocy will make things better for ALL of us.
For starters, traffic jams would be all but history once all cars are driverless. Our major highways can handle the amount of traffic that are on them at any point in time, but the jams are initiated by
people. It only takes ONE clueless idiot who doesn't merge properly as traffic is building into rush hour (ie, the "Oh geeze, there's not a 2KM gap for me to roll into at 40KPH so I'd best stop on the onramp and then out of eventual desperation roll into traffic at half the flow speed!" dolts out there) that initiate traffic jams. It happens
every freakin' morning at many highway onramps, which not coincidentally is where traffic jams start.
That, and the "I'm the most important person on the planet therefore I must weave from lane to lane to get 20 feet ahead of you all while alternating from rapid acceleration to desperate braking" drivers as well. And there's more - add in 1 stupid unnecessary "I was putting on my makeup and got distracted" fender bender sitting in the middle lane, and blammo...you have our average daily traffic jams.
Remove the driver from all that. Computers change lanes only when necessary and beneficial and do so perfectly and without speed fluctuations, cars merge and exit seamlessly without any disruption of the flow of traffic, accidents due to inattention or sheer stupidity are virtually eliminated. Traffic flow stays uniform and at a constant speed. Nobody is more important than anyone else, short of perhaps emergency vehicles. It's not difficult to imagine how much better traffic would flow.
