In that same vein but perhaps more subtle, what of the social failsafes? I keep imagining this scenario (one which I run into consistently in the Bay Area), where I am looking to merge into the lane to my left because my lane has ended, and nobody will fucking let me in. Does the automatic driver have a level of aggressiveness that it follows? What if two automated drivers have the same level of aggressiveness and one wants to merge and the other won't let it? Do they just stop, resigning themselves to an endless loop of near catastrophe because neither will yield? I'd love to know more about exactly by what driving conventions these automated drivers abide. I think it'd go a long way to help people understand how such a process could be automated at all.
