>> "...convert all speed limits to suggested speeds (thereby abolishing fines for speeding)"

The State of Montana had this until the late 1990's, when the Fed's finally forced Montana into having a speed limit again by threatening to pull all Federal highway funding.

Other fun facts are that you could get a driving license at 14 years old (or a "ranch driving license" at 12 in some semi-rare cases), there was no seatbelt law, no motorcycle helmet law, and no law against drinking and driving[0].

[0] There was a law against being drunk while driving, but not a law against drinking while driving. This lead to the classic canard: "How far is it from Butte to Helena?" "Oh about four beers."
