What *would* be nice and probably more realistic would be variable speed limits, particularly for super straight and typically empty sections of road like the 401 between Windsor and London (empty during non-business hours/weekend mornings) and the 402. When I'm driving back to Michigan in the middle of the night and I'm the only car in either direction for miles there's no reason I shouldn't be able to go 180 if the road and weather conditions allow it (here's where the variable part comes into play), instead of locked in at 120 because anything over that and you'll get pulled over by a bored OPP officer.
