When you gotta go, you gotta go.
Obviously the guy couldn’t wait. Perhaps he should have used the facilities prior to taking this 600-hp BMW M5 pre-production model on a Nurburgring test run. But he didn’t and realized, or rather felt, his mistake minutes later. Problem then was that he was smack dab in the middle of the Green Hell. But no matter. He pulled the M5 tester over anyway and proceeded to do his thing. Car spotter Supercarsfromeu happened to be there filming what he thought would simply be an M5 running some laps, until something unusual happened.
Unusual as in it has never been seen before. Beginning at around the 2:10 mark, you can see the car suddenly deviate off the track and onto the grass. There was nothing mechanically wrong with the M5; all systems were functioning properly.
But something was the matter. After backing off the pavement, the driver got out and walked over to some nearby trees, did his thing, then hopped right back in and gunned it. He probably figured no one was watching. Conduct unbecoming a BMW test driver? Nah. When you gotta, you gotta go.
