There have been a number of things where bumps (or otherwise non-flat/smooth) surfaces have helped aerodynamics; golf-ball dimples being the most recongizable example. If I recall correctly, some of the speed-skaters in the Olympics a few years back were wearing some whiz-bang body suit that had some "deformations" under the arms or somesuch for the same reason.
Uhm... yeah.
With 2 out 3 homes in the town over $500,000, do you think there *is* a walmart there?
There was a little town I grew up next to in FL that had a nasty reputation for tickets for anyone going over the 25 MPH speed limit, even 1 MPH. And the reputation was well deserved; the town was small and they enforced *EVERY* law to the letter; rolling stops, speeding, turn signals, etc. Result was exactly what you said, no one went there.
And that was precisely the goal. They don't *WANT* people in there.

What's safety got to do with it? It's the People's Republik of SF, NOTHING gets in the way of Social Engineering, comrade.
