Look at the damage to the WALL!!!

... man that was a very, very hard hit, no chance

.
It would be safer if the wall was run parallel (see attached pic. and red line) to the track all along that straight ... yes it would be much closer to the track but they would have possibly survived the glancing blow (or 3).
The wall needs to be relocated before more cars run there in anger IMO. Such a simple and cheap solution
