Last year, in the ALMS race on the redesigned Lime Rock pretty much everybody cut the chicane where the West Bend was before... Just as an example that it can happen, but if the stewards are strict you WILL get a penalty...
Anyway, there are 2 things which are wrong in LfS:
1. People consider rumblestrips and run-offs are part of the track, which they are not, and
2. The rumblestrips themselves are ridiculously oversized - I've seen only a handful IN THE WHOLE WORLD wide enough to park a whole car on them, yet you can do that easily on a vast majority of them in LfS... The only track where the size is about right is Fern Bay - but those are way to steep...
