A great way to legitimately "speed" down the motorways and highways. There's not much more I can say without spoiling it!
Tired of getting stuck in slow moving traffic?
Want to have your own lane on the M1?
Simple, tie these balloons to the rear of your car.
Belt it down the M1 or any other road you wish to drive fast) and watch other car drivers freak out and simply get out of your way!
When you get stopped by the police, tell them you thought they were real!
