When you win a race, the computer uses the elapsed time of that race to 'seed' a random number. This means that your ET is put into some bizarre and complex formula determnined by the programmers, and is reduced to a particular raw number rather than a time format. The full range of possible results is divided into parts based on the available prize cars, and these are each assigned a portion of that range. I do not know if the portions are equal or not, but I suspect they are. When your ET is crunched and the machine comes up with the number, you are awarded the prize car corresponding to that particular range.
