I would like to be able to set different strategies for each stint, I mean to can choose to start with low push and after the 1st pit-stop to have medium Push! It is useful if you cannot be live during the race!
Pilot atttibutes I would add ability regarding weather conditions: heavy/medium/low rain high/low temperatures. Then also on Ability on qualifying and start.
Add more kind of tires as in real F1.
To be more realistic I will love to have incidents safety car, pilot errors, broken engines or tyres (in reality it can happen also if the car got all new components)
