Not much of a realistic fix, is it?
Driving isn't intrinsic. Transportation is important but has multiple solutions.
Mass transit will NOT reduce auto transit: any driver who chooses to take mass transit will be replaced by a new driver on the road.
Civilized countries already solved this problem.
So if you're just building out transit while keeping road capacity the same (less common with dedicated bus lanes or light rail, because space for those is often created by converting former car lanes, but with "other off-grade transit" modes you need to make a conscious effort of reducing road capacity if reduced car usage is your goal), it's entirely possible that public transport use increases, while passenger miles travelled by car remain the roughly same long-term.
