Waymo can be found on the roads in NW suburbs of Detroit (Novi). Admittedly I did not see them much over the winter. Point is simply that they seem to be testing in the more ‘real-world’ conditions found in the Midwest. I have no idea what the progress is or number of autonomous miles driven but they do have equipment in the field in Michigan.

Hopefully as other companies advance they’ll also move to Michigan as an ideal test bed and bring the crossroads of tech and auto to Michigan.
