Scawen, while you're at minor layout/objects issues, could some tires barriers become "non movable"? either as a concrete barrier, or still as tires, but just don't let them scatter when hit?
The specific barrier I had in mind is the last tires barrier before the main straight at the exit of AS3 chicane.
The thing is that this specific chicane is already notorious because you have to commit to your line to be fast through it, but the smallest of miscalculation, and the tires get hit, and everyone following you is having to cope with sometimes impossible situations of tires all over the road, when you're at 180KPH with very little margin to maneuver around them, if at all.
This specific barrier, because it's tendency to scatter the tires, and it's location, mostly hurts the drivers following the one who hit the tires, and it's even more annoying when the one who hit the barrier is a backmarker driving just in front of your nose.
So, if these tires can be "connected" together, and to the wall while you're at it, I think it'll improve the situation at this chicane greatly...
