You can't improve the transport until you start building high density housing, that's not 10 units per acre.
Go for 35 per acre sure, you don't need 70 parking spaces then, because (assuming it isn't literally 35 units in the middle of suburbia) you get commercial and transit (people still got to get to work - maybe in WFH stays around that will change)
is it 1 car garage or literally, a garage with no driveway? if a link to a specific example was mentioned above in this thread i missed it
