when ur so fast first speed bump doesnt really work.
This is why second speedbumps exist at same place. Do you really think cars will speed up that much fast at this close range?
It will not, they add two speedbumps together so it can really stop the cars.
Speedbumps rougly stops %60 of cars speed.
i dont really know why you dont know this. Im telling this considering your 73 id
