Foot brake drag racing

Practice, practice, practice. In your personal vehicle if you are caught at a red light, start to lightly power brake when the cross-light turns yellow. Then when your light turn green just do the launch part and then back off.

Also good to know how the car reacts when you let off the gas in full throttle. Is the parking brake working?

If you have a forward pattern valve body, you can downshift to slow your car down (if the rpms aren't too high).

Maybe someone local has a Christmas Tree on private property where you can powerbrake launch.
