this is tech ... so people can stop in b/w then speed again .. lol .. just kiding

instead of spending so much money on this ... they can ask manufacturer to not to make car with 120+ speed .. simple .. but nah in that way they mess with corporate ... but they control individuals ... who don't have enough power..

its a human nature .. if you have power/speed/space u will use it
