To be fair though, the dude in the video wasn't exactly daring drivers to hit him was he? He was being a cock, for sure, and was asking to get hit like that, but your generalisation that it was a BLACK thing was a little random, as I've seen plenty of people "sauntering" across the road making...
Other people that constantly walk slowly across the road causing vehicles to slow down: Drunks, Hippies, Old People, Children, People with Dogs, Mothers with Pushchairs.
Well, pretty much anyone really.
I love Hradlec Kralove! In fact I'm going there again this year hopefully. Massive 3-day Hip Hop festival called Hip Hop Kemp every August. Have no idea what they would be doing in Brighton though...
