I'm not sure what the others think, but could I suggest that damage is turned back down to visual again, especially in the open wheelers. The current performance impacting setting seems to be ruining drivers half hour of fun, both those with damage and those who hit the hard to control damaged cars. If you haven't got your pitstop strategy set correctly it can take various amounts of time to repair too. It's not actually that realistic having to crab around for part of a lap with major damage then get it all repaired.
It's better to keep the drivers smiling rather than having them drop out frustrated with wonky wheel syndrome.
It's a shame there's not a "light" setting like in GT where your car receives damage for a short spell then repairs itself and you can carry on. Again not realistic but it would be a good comprise between suffering some loss of control and performance but being able to continue to race.
The full setting is an option, so if you crash badly you're probably out of the race. But as I say we've only got the one race.
And while you're at it you might perhaps accidentally switch off the track limit penalty too.
