Computers are really good at measuring stuff like 1320'. Speed sensor on a computer car is a output, it could be used to measure the distance of the race track down to a fraction. You would need a real time device to tell the computer where the the car was on the track verse what the computer is seeing from the speed sensor and compare them, say the real time sensor tells the computer that the car is at the 330' mark but do to tire slip the the speed sensor says it is at 331' you program the computer controlled throttle to slow the car down, or speed it up to what the car needs. And if you had enough reserve built into the car, it would react very quickly.

Optical speed sensors are available that are very accurate, accurate enough to be used in law suits when car company's are being sued and need precise data. That sensor would be the only sensor that would need to be hidden on the car. And that sensor is about 2" long by about 1" wide and 3/4" thick.

How much would it cost? a lot less than a 100k stocker.
