Easy. Just elevate the rear wheels (Mustang) with jack stands, get in the car and have at it. However, pray like hell the car doesn't vibrate too much and break away from the jack stands. :Q
In my area, most of the service stations perform emission tests. As part of the emission test, the vehicle is required to sit on "rollers" installed in the floor of the testing area. The vehicle is then secured with a tether and the vehicle is brought up to highway speeds for a few minutes until the test is complete.
If the individual with the Mustang utilized some artificial means for getting the vehicle up to 140 M.P.H. - hopefully, it wasn't truly jack stands because that would be way, way too risky to do.
