As someone that grew up driving in the midwest I get a little nervous about autonomous driving being developed in California. It's a bit of a cliche, but CA drivers are notoriously bad drivers in winter conditions.

Of course the rational side of my brain knows there are brilliant people from all over the country (world?) working on autonomous driving for these companies, and they will have to do testing in all weather conditions across the whole country.

Perhaps it would help relax fears if companies like Google or Tesla opened (and publicised) an all-weather driving lab in someplace like northern Michigan.
