Reaches 200 mph. Apparently it is tethered to a pole in the middle. Is this real? The flag seems to be blowing at a normal speed...

Apparently it's geares WAAAAYYY high as you can hear the engine bogged down when they are push starting it by the tether.

Totally doable, but that has to be some serious tensile strenth cable to not snap with the centrifugal force the car is creating
