The purpose of early upgrade is to quickly catch up to 1st and start blocking, tripping and even crash those catch up cars. Then slow down to wait for them to catch up. Once they catch up, block, trip them again to set longer lap time.

With this method, from Stage 1 to 7 in my race, the fast lap for all cars are above 30sec for Richmond International Raceway & above 1min 10sec for Indianapolis Motor Speedway.

This is how I show down the BOTs by not wasting time Retire & Retry.

Also, how much you upgrade will not affect the BOT's AI.
