With the Tilkedromes and other tracks having problems with drivers exploiting track limits, especially on Vettels recent misdemeanour. How should tracks run off areas be changed to offer less reward for drivers to exploit track limits and still be safe and give drivers a second bite of the cherry, however be given a penalty for exploiting track limits.
I think there should be a 1 meter wide, or ideally 2 meter wide strip of grass-crete, as i think the grass will slow the drivers down as there is less grip, and also when they put the power down, a specially designed concrete mix, or a design that rips away at the rubber compound as well if the driver puts the power down in the wrong manner.
Thus giving a penalty of around 4 to 10 seconds immediately as well as the penalty of killing your tyres as well.
The tracks are safe enough at present, all that is needed is a little tinkering in order to make drivers adhere to the white lines and have more respect for the track limits as the extended run off areas have became an accepted way to gain an extra 3 tenths or more at certain points of the tracks.
As for the extra run off areas, id probably change them to a very abrasive tarmac as well that gives a penalty for using them as well, enough to make the tyres loose a extra half a lap over a stint in degradation.
What can be done to keep the safety in the tracks, but also give a penalty to use of theese areas?
