WA allows renewal by mail without even stepping into an office.

WA also allows transferring of drivers licenses without additional testing. To me, this is the most problematic part, because different states have different rules around priority, proper usage of the left lane, etc. and WA is a transplant destination, and the resulting mix of driver backgrounds is chaotic. As a general example, in WA pedestrians have priority at all intersections, including where there is no visibly marked crosswalk, but this is not true in all states.
