Please, tell us one country in the world that doesn't need cars.
Many, may be less dependent on cars than the U.S. . But no country is independent of cars. Using such hyperbole doesn't help the conversions. It just deepens the trenches.
That's not the same kind of scheduling. You can miss a bus, and be forced to wait for the next one (which will at 15 minutes minimum), but your car departs exactly when you're ready to leave whenever that is. After that, then you add the 15-30 minutes drive time (or more for a bus, if it's not an express bus and makes intermediate stops or if it takes an indirect route for your itinerary). This is so obvious I'm surprised I have to point it out.
