Damage 100% could be a way. If you know a small hit can damage your car, you must be more careful. I’ve took part in some raceroom’s events  and drivers were very careful and smooth.

I think this has been proven to be the opposite of helpful to people who are actually trying to be careful who want to continue racing. Drivers who are careless will continue to be careless regardless of the damage percentage. People who dive bomb or similar aren't dive bombing because they think they'll be fine due to damage being set at 60%, it's because they are bad drivers.

60% at least means that incidents don't ruin the entire 40-90 minutes for anyone involved.
