Traffic lights are likely to vanish as self-driving cars establish a safety record superior to humans, leading to a ban on non-self-driving cars.

Now there's an interesting item I hadn't expected and I suspect it to be true. I'd guess that by 2050 (or earlier) most cars will be self-driving. There will be a period of overlap where it's still legal to self-drive, followed by the outlawing of self-drive cars and the removal of traffic lights, as you predict.

Let one speck of dust get into the chip and it’ll drive you right through the intersection and into an 18 wheeler.
