Because Ascari is a private track, owned by the members of the exclusive Ascari Race Resort, it is not governed by the FIA and the kerbing is not painted in the regulatory red and white that they would be in an officially sanctioned track. If these kerbs were painted red and white we would automatically consider them as part of the track despite being outside the white line.
The way they are designed means that to stay within the white lines the driver has a very narrow angle of attack and I, like others, can foresee alot of problems with cars overstepping the boundries if they don't approach the chicanes cautiously enough. I can only imagine the nightmare it's going to be at the start when a full field of cars converge on that 1st chicane jostling for position to take that single line through.
I will abide by whatever ruling is implemented but I agree that a pragmatic approach to this would make sense. The video that Fizzer posted, and others easily found, illustrate how those managing the real track have dealt with the situation.
