It ' s quite weird . Bytes 1 , 257 , 513 and 769 cost 270 . 512 and 1024 cost 8 . WTF ? 417 , 705 and 961 cost 207 Other bytes where 32 n 1 are 206 All other bytes cost 72 . <| sep |> A modern economy car with good tires on a dry road can generate about 0 . 9 to 1 . 0 G in braking , which would mean stopping from 60 mph in 120130 feet . A really high performance sports car or supercar with sticky compound tires , big brakes , and a little help with aerodynamics can generate over 1 . 2 G when braking , allowing it to stop from 60 mph in less than 100 feet . Now apparently an F 1 car can experience up to 5 G of deceleration when braking , which would mean it could stop from 60 mph in just 25 feet ! However , as much as the low weight and large sticky racing slicks help , the majority of an F 1 ' s insane grip is provided by downforce which increases with the square of speed . There is 4 x as much downforce at 2 x the speed , or 2 x the downforce at 1 . 4 x the speed , etc . So braking hard from 200 mph might register the full 5 G deceleration momentarily , but from a lower speed like 60 mph to rest the downforce would be far less effective . It ' s possible the average braking G from 60 mph might only be 2 G , which would stop it in 60 feet .
