I would believe that people directing traffic usually use only a handful of signals, but it's certainly not a universal truth. This is one more case of the 80/20 problem that self driving tech keeps running into.
Sure it's probably feasible for cars to handle hand signals in the happy path, but anything outside of that will be disastrous. How will the car understand and communicate with a person who doesn't use the standard signals, aside from having some level of intelligence?
