Just do quick race off line w/ zero competitors as you use it for practice as well as win every time and before you know it you'll have as many cars as you want as well as a bank account filled w/ space bucks.
The AI seem to think the objective is to take you off the track. The Bugatti Veyron invitational on the nurburgring must be the most expensive demolition derby ever 👎
I demolished the AI when they started to get like that. Just take them out and turn damage to visual, that way your car won't get mechanical damage and you can play against the computer on equal terms. If you have damage on full, you might as well give up in the Bugatti race. But that thing is capable once you get it down. 6:40's around the ring is no problem
The aggression related challenges are linked to aggression related events, they don't count towards anything else and you're free to ignore them if you wish. None of the stars you gain from them (or in drift, etc) are necessary to get anything.
The single player can get annoying.
