Because people can learn on the fly, and these systems can’t. Sure, you can aggregate the data from a fleet of cars and use that to train a better model (or set of models for vision, driving, etc.) that updates the old one, but that process takes time and isn’t as immediate as a human reaction. Not saying it can’t ever happen, but rather that it’ll take a lot of time and effort before a self driving car can handle extreme weather, rather than the calm conditions of California (which, to be fair, took an awful lot of work to get functional there, too).
