Seldom (if ever) is there the rather obvious suggestion to limit autonomous vehicles to simple point to point 'highway' trips; but that's exactly where and how it should be done for the foreseeable future, if it happens at all. That is, the (literally) lethal mistake is to introduce autonomous vehicles into the complex and chaotic world of city driving. The next time you drive in the city consider how many of your decisions are predicated on understanding subtleties (some might occasion "stupidities") of human nature: "Is that guy looking at the person as they're talking on the corner? If so, they aren't as likely to start across the street" "Is that a child's toy which just bumped a bit into the road (to be chased by a child) or just a blown leaf?" "OK ...four way stop: it's that guys turn, but, he's got a cell phone in his hand he's consulting" ...etc. So, start out with truck loads from freeway exit 113 to 114, then if that works, exit 117...
