I think people vastly overestimate the challenges of weather conditions for self driving. With modern car tech (traction monitoring, ability to redirect torque to a specific tire, ABS, radar) an automated car is going to have an easier time navigating snow/ice/rain than a human driver.
The real challenges when navigating city streets are the human ones – delivery vehicles blocking lanes, municipal worker fixing a manhole with a single cone to redirect traffic, pedestrians/bicyclists appearing out of nowhere, no one following traffic signs. This is the kind of stuff that tests "intelligence".
