I think it is the track limit rules that are the problem, I really don't understand how UK Motorsport has got into the position it's created such a ridiculous rule in the first place. I can understand there's a few places where track limits are required, for instance where there's a run off for safety reasons that could be massively abused otherwise.
For a track like Brands Hatch there's nothing like that, the whole circuit has natural limits that do the job perfectly. There's so many things wrong with unnecessary track limit rules. From a driving point of view it feels crap driving to an articially painted line, from a spectators point of view it also doesn't look so spectacular. Driving a car to the natural limits of the circuit is much more exciting to both do and to watch.
As we saw on Sunday, it's also bad from a spectators point of view to have what was a thrilling dice for the win instead decided by an official looking at whether a car crossed a painted line or not. It must be gutting and so frustrating for a driver to lose a win like that. Whereas if you lost it because you ran wide, put a wheel on the grass or in the gravel you're left in no doubt it was your mistake, you can take it on the chin and resolve not to make the same mistake next time.
There was a farcial situation in the end of season FIA F3 showdown at Monza last year, where multiple track limit penalties kept getting announced one by one during a red flag stoppage. Penalites that changed the points scored by title contenders and potentially affecting the outcome of the championship.
