Nah, I've lived in two places now where walking or cycling to get your groceries (or, gasp, just having them delivered) is way nicer. Because it sucks to drive and the store is just around the corner.
You do know that much of the US was built on the rail network and plenty of cities had transit systems that were the envy of the world until they decided against those in favor of the car and bulldozed city centers for parking? You're making it seem like this is impossible when it used to be the standard.
