I came back from a few days on the road to my car at the airport covered in about 2-3 inches of wet snow. My wipers were on automatic an freaked out so i menued through the several soft buttons to get them off. Opened my trunk to have all the snow on top roll onto the now covered rear window and all that slide into my trunk. Trunk is unusable on a snow day compared to the prior cars I have had with a similar configuration. No thought was put into a larger moat between the rear window and trunk. Suffice to say, keep your Model 3 garaged or move to the Bay Area.
