Slow Is Fast
The fastest car on the track will put in the slowest lap times if the driver can’t keep it off its roof and away from the pipes. Driving faster than your ability to control the car precisely will result in longer lap times, even if it feels faster. Try this experiment: Time yourself for 10 laps, driving as fast as you can from turn to turn; then time 10 more laps, going only as fast as you can manage without making mistakes, whether a “mistake” means hitting the boards or just overshooting the turns. Dollars to donuts, your “slow” laps will be faster overall.
Driving faster than your ability to control the car precisely will slow you down, not speed you up.
