A guy in Australia had his Scottish mother visit from overseas for the first time, so of course he took her out in the desert and let her ride on the outside of his car, while he was going well above 70 miles an hour. She was hanging onto the driver's door, and loving it. At the end it sounds like a crash, but that's actually just wind noise. When he says "we got 100 at the moment," he's talking about kilometers per hour.
Yea, that's normal.
