> As someone from a Midwestern state, I fear that all the self-driving car development in California is going to miss the important edge cases we experience here. Snow, plows, salt, dirt, heavy rain, etc all destroy the visibility of lane lines. You overestimate the quality of roads in California. :) In San Francisco and Oakland the roads are, quite literally, falling apart. Take a ride on 880 -- straight up four lane high way with virtually no road markings.
