There's a relatively simple fix for lane markings, that would help autonomous cars even in good weather. You know those reflective lane marking doodads they embed in the road surface? We start replacing them with magnetized nails that are pounded into the asphalt in intervals. Sensors in the car could recognize the lanes even in deep snow or pea-soup fog. And homeowners could easily outfit their driveways with a trip to Home Depot.
