It's not, if you build correctly. It's only "faster" when you spread things out into suburbia.
Is it faster for you to get in your car and drive next door or to just walk over there?
Of course its faster to walk.
Walking is faster.
You can't just say "driving is faster" without qualifications.
> your car is available virtually 24/7
So are your legs. Walk and bike.
I don't see the relevance of many of these other items you mention. Who cares if you can personalize your car? I'm not saying cars should be banned, but we should stop optimizing for them at the expense of everything else, especially when they aren't necessary.
