Riding through downtown San Francisco yesterday on the way to a trade show at Moscone Center, we noticed what appeared to be some college-age guys riding on the back of a van. Not too smart that. As we got closer, we noticed a couple of things about this stunt: a) the riders were doing this without the knowledge or permission of the driver, and b) the van belongs to the SFPD.
Sorry about the finger in the picture. I only had a moment to fish out the phone and snap the photo; both cars were moving at the time.
My best guess is that this was a fraternity initiation or something similar. Riding the back bumper of a van through city traffic is extremely dangerous, of course, but just the sort of thing kids of that age would try. But on the back of a police van? And what does it say about the driver that she was unaware of what was going on? As the hipsters say on the Interwebs these days: FAIL.
