Yeah, they would presumably take public transit or bicycle instead, as long as those options are feasible.
for example this saturday when i wasn't in a hurry and went from Antibes to Nice.
I took a bus(1€), then train (6.8€) then metro(1.7€) for a total of 1 hour 15 minutes and 9.5€ (multiply by 2 for the round trip) it would have been a 20 minute motorcycle ride.
