There's more worth going to within a 10 minute walk in Siena the there is within a ten minute drive in Houston.
NYC, London or Tokyo also work as examples since traffic moves at a snail's pace. It's trivial to beat a car on transit and a moderately fit person could jog faster than a car there.

Same with Siena (I picked just random points "Hotel Athena" and "Farmacia Ravacciano" as they were highlighted on the maps) 17 mins by car, 26 mins by transit (though walking is faster than transit and biking is faster than car, apparently you cannot drive through the city, very progressive).

Walking is almost as fast as driving and biking is faster? Not sure how this proves your point, sounds like it is working as intended
This just isn't true, everything breaks down and driving becomes much slower during rush hour due to inherent limitations of, you guessed it, physics.
See my other comment about my rush hour bus commute in Portland, the bus was faster than driving because of dedicated bus lanes. Driving is only fast if there isn't traffic AND there is ample parking close to your destination.
Siena bans traffic out of necessity, not just on a whim. There simply isn't space for cars.
