Yes, they are. Do an experiment, drop ten points randomly on a city map. Then plot routes between them, using Google for transit and cars.

For most cities, cars will be about 2-3x faster. For three simple reasons: no walking, no waiting, no stopping.

And that's the paradox. Cars are better than transit, yet modern cities are hell-bent on destroying the car infrastructure.
