Re: cheating
"and if you bought a car , you should be able to drive at 140mph with the seatbelt off?"
Yes, if it is off the public road.*
*Leaving aside that "drive at 140mph" and "with the seatbelt off" are not connected at all - yes, both are illegal in many countries, but independent of each other i.e. driving at 140mph on a public road with a posted limit is illegal regardless of whether a seatbelt is worn, and driving at 14mph without a seatbelt is also illegal.**
** Also, in practical terms, driving at 140mph does not require a seatbelt to be worn, and wearing a seatbelt does not of itself make driving at 140mph possible.
