one thing that i'm curious about is how autonomous vehicles will handle traffic jams. i think it was the washington post that had an article within the last 2 weeks discussing what an autonomous vehicle would have to do if they hopped on to 395 in DC and then had to get off at an exit a few hundred yards down on the left lane, 3 lanes over. that's not a lot of time and space.
of course, the logic there is that you *have* to make the exit, which most people subscribe to. instead of passing the exit and taking the next available one in order to make safer traffic maneuvers.
i see it all the time. hell, i saw it today when a van missed an onramp but decided it would be a great idea to try and merge from 0mph with traffic that's 60+. and the van was at a ~45degree angle relative to traffic. i honked at that dumbass driver fo sho since there's another ramp within a mile.
