Driving is the most comfortable, convenient, and fun mode of transportation. Walking and biking can be OK but only for traveling relatively short distances in good weather. Mass transit is inherently unpleasant. No matter how nice you try to make it (and most mass transit systems aren’t nice) the fact of the matter is that passengers are still stuck in a crowded box with a bunch of strangers and limited to traveling to the mass transit system’s destinations on the mass transit system’s schedule. Compare this to getting into your own car and driving wherever you want, whenever you want…
I currently live in a place too crowded for driving to be practical - I get that places like this need mass transit. But needing mass transit sucks!
Of course it’s great, that’s why it’s popular.
It’s the effects that are bad. Traffic. Needing parking lots that are bigger than the store, restaurant, office, etc. Pollution, smog, warming (hows your summer going?). And expensive (believe it or not it’s subsidized, if drivers paid how much it actually cost it’d be like increasing gas price ~4x.) House plots that need to be huge to accommodate 3+ cars. Apartments need parking lots as big as the building. Noise so you can’t enjoy being outside. Places being ‘dead’ because there’s no third place and no people around.
