If those accident categories are the ones that don't include fatalities or even injures (which is likely) then it's a win. Computers and computer vision systems are probably less likely to fail on a highway, than a human is. Computers can also integrate road data in ways that humans can't. To be honest, I think the argument you're offering is just the reason why we'll start seeing automation of route-following vehicles first. Trucks, buses, and taxis going to airports and hotels, don't necessarily have hard route-finding problems. You also say things like "Can't build a secure internet" as though that's ever been tried, or necessary in this case.
