Chassis dynamometers in operation aren't exactly known for providing the safest areas where car fans can sit and watch and/or hear a sports car “getting it on” while sitting still (the car, that is).
There have been numerous examples of cars falling off the dyno, out-accelerating and sometimes even out-breaking the dyno rollers, or with their engines catching on fire.
The following video depicts another reason for not sitting near a car whose wheels are spinning at close to the vehicle's top speed while it's technically parked on top of a dyno.
The Mercedes-Benz E 55 AMG (W211) which appears to have a highly modified engine and aftermarket wheels is getting tested in a park with a mobile chassis dynamometer, while a curious crew of people are filming with their phones and probably expecting the dyno's results.
One of the car's rear tires gets pretty much destroyed at about the 0:20 minute mark, prompting the gathered bunch to disperse in the span of just a few seconds. Fortunately, nobody seems to have been hurt, but it just goes to show you that Gremlins aren't found exclusively on airplane wings, but on dynos as well.
