They've done some testing in Buffalo NY, which gets more snow than pretty much anywhere in Canada. The hard part about self-driving is dealing with / predicting the behaviour of humans. That's something that humans are good at and robots are bad at. And SF has more weird human behaviour than anywhere in Canada. Predicting the behaviour of vehicles in snow is something computers are much better at than humans. Solving the sensor problem for driving in rain/snow also seems like a standard tech problem where vehicles can quickly become much better at than humans who are limited to mark 1 eyeball.
