First, you need a car that will do 140+mph. Then you need the traffic out of the way. My best was 135mph in a rental. Can't do it in my car, but before I leave I want one run exceeding 150mph.
My bird has done 140, -with power to spare... -I wanna exceed the 160 speedometer...
-Hence the need for 3 point seatbelts -just in case ..
-Not that it would do that much of a difference w. that speed..
