Same way as usual. If you're going too fast you crash ;-)
How do you drive your car in RL? If the posted speed limit was 50mph, would
you take a sharp corner at 50mph, or would you use your experience & slow
down a bit?
I tend to drive using the***pit view when racing, but in practice,
particularly at a new track, I'll switch to the outside view periodically to
check how close I can get to a kerb, or to check the speed in, through or at
the exit of corners to see if a setup change has helped.
But when I'm racing, I just go as fast as I can until I've caught the car in
front (if I can), and if there's a big gap (or I'm in the lead), I run just
fast enough to stay there. The speedo doesn't come into it.
