If anything, emergency vehicles have been hampered by the rampant proliferation and deregulation of cars, because it makes it harder for them to get to their destination quickly and safely.
Hell, half of the time I can’t move as quickly as I would like to through the city with my bicycle it is due to cars being in the way of moving quickly and efficiently. And that is a lot smaller than an ambulance.
Most of those places would work just fine with a combination of trains for long distance and bicycles/walking for local travel too.
