The car was going 75 MPH as far as I could tell. A bit fast. But generally it seems to be keeping in line with DMV guidelines. https://www.dmv.ca.gov/portal/dmv/detail/pubs/hdbk/traffic_l...
I guess the multi-lane open highway is the reason it's ok? Does that make those multi-lane open highways a free for all? No concept of a fast lane, overtake wherever you choose?
