When you own a McLaren, the world is your toilet. I think that was McLaren's ad slogan for a while there, and even if it wasn't, it's surely the personal mantra of the pea-bladdered urinator/McLaren MP4-12C owner in this video. I bet he has it embroidered on a throw pillow.
Now, I'm a firm believer in that having to pee while driving is downright dangerous — it's been proven, with science, even. So I applaud the man for three things: taking the time to color-match his outfit to his car, his responsibility to make sure he's not driving while feeling the urge to urinate, and his complete and total lack of any shy bladderism, peeing freely and wantonly right there in the open on the side of the road.
