> The scary bits of self-driving is person detection, crossing detection, roadwork detection... Your point it very astute. Among a few other ML/AI MOOCs, I completed Udacity's "Self-Driving Car Engineer" nanodegree - so when I'm out driving, I often come upon situations where I wonder "how would a self-driving car navigate this?" Today, driving in to work (note: USA), I noticed one intersection I've been through many times before, and that question came to mind. The intersection is interesting, because on approaching it, the road curves to the right, and you can actually see one of the traffic lights on the left before you even see the intersection. By the time you see the intersection, you're already on top of it. So as you round the curve, you see the lone traffic signal (red/yellow/green); if it is red, do you start to brake, or do you wait until you can "see" more traffic signals? If you wait - will you have time to slow down and/or stop? ...and so forth. This and others are all kind of "edge cases" that will need to be trained on, and/or perhaps other cues for self-driving vehicles installed or set up so the vehicles can navigate such areas successfully. I know when I first went through the intersection it was a bit of a surprise; it's not a very safe intersection (going home in the opposite direction is not any better; in that direction, you're headed downhill, have to cross the intersection, and immediately start turning to the left after going through - the curve is really abrupt, and you have protected/unprotected left-hand turns both directions, etc). |
