> I think the reality here is that we don't have the fuzzy logic and AI to handle snow covering up lane markers...
True, but improved AI isn't the only way to address such problems. For instance, thermal cameras can see through light snow, so those may become standard. Also, something like RFID embedded an inch or two below the road surface could serve as marker enhancers. If all else fails, GPS and highly accurate maps can stand in for road markers in many areas. Besides, snow won't be as much of an issue if self-driving snowplows get started shortly after snowfall begins.
