It's not more convenient. It's only more convenient if the infrastructure isn't there. Dodger stadium is a classic. It's the stadium with 12 stadiums worth of parking lot around it. Some stadiums in Europe have 3-4x the capacity of dodger stadium and no parking. That's because it's convenient to get there by public transport. The US specifically makes zoning laws so people need cars from the isolate suburb to the yuge department store.
Even gas stations don't pay for themselves. Gas would not be "profitable" or affordable for anyone if our governments didn't spend billions subsidizing it.
