I was just thinking the same thing -- "this will never work in Boston. We fear and hate painted lane markers." But it turns out that something like 90% of miles traveled are on highways.[1] So what if you just limit it to limited-access highways recognized by the GPS? That covers a huge chunk of miles traveled, and you have actual vehicles out there a lot earlier, which will teach you a lot. And highways kill (I think) tens of thousands of people a year, so getting more reliable drivers out there can't come any too soon. I'm also thinking that the AI will have to be pretty damn robust to go into production, whatever this article says. Whether or not there are painted lines, it will have to share the road with other cars, so it will have to be pretty smart in order to do anything at all.
