If you know how physics work then you would know that if a car moved that fast the air particles in front of it wouldn't be able to get out of the way fast enough and a vacuum would form behind the car. Nuclear fission would begin happening on the air in front and just as the vacuum behind was being filled with air again a HUGE explosion would devastate the area around for 1.5 miles.
BUT since it's a videa game and not real life all it did was feel TERRIFIC to go so fast!! GREAT game! And great work! You executed this very well! Good luck to you!
Also I'd appreciate feedback on my submission if you get a chance!
