While we were driving around in Melbourne over the weekend, a question occurred to me. How would driverless cars cope with those large intersections controlled by a conglomeration of traffic lights and red and green arrows and stuff? We considered that they might take their cue from the control boxes, but I doubt the infrastructure is really set up for that.
I've asked this in the Holiday Forum but I've pretty much just been told how fabulous computers are and all that and that lots of companies are working on it. And that if they can do facial recognition they can do this. I still am inclined to think that this level of discrimination of the visual noise is unlikely to be currently possible.
I take my suspicions from the poor progress in producing artificial retinal components.
