And yet it doesn't matter enough that drivers (riders?) are selected the same way as horse jockeys.
Its a pretty damn big deal in some motorsports. I've heard 1 kg is worth .03 seconds per lap on the average F1 track. Doesn't sound like much but thats just about 2 seconds over the course of a race per kilo. Most drivers are smaller than average and I've heard stories of them starving themselves leading up to a race weekend.
Their height also matters the higher the drivers head the more drag.
The heavier the car the less the drivers weight will impact performance, and that goes even more so if your mostly drafting. So its not too critical for NASCAR for example.
