Did a couple more multiplayer mid-engine races, and had my safety rating drop from S to A for the first time ever. There was no contact with any other car all race, so it had to be caused by the two penalties I got for cutting the track by the odd pixel. It was wet conditions so it was very hard to see the detail of the kerb edges, and I don't drive with track limit markers on because I think they are incredibly ugly and completely ruin the immersion of the experience. I got 3.6 seconds of penalties for the 2 cuts, which exceeded any time saving by a massive amount, but it showed me a message after the race telling me not to gain an unfair advantage by cutting corners! Isn't the whole point of the penalties that they should be bigger than the time saving, so that there isn't any unfair advantage? I estimate I gained no more than 0.2 each time, so the penalty was almost 10x the time saving, and almost lost me the race, so I'm not sure why they need to impact safety rating when there's already no advantage from cutting.
Just did a lap in rivals to see where the limit is on that corner, and it's so much easier with the track limit markers on. Maybe they could let us adjust the colour/brightness of them so we can have them turned on without them being quite so visually offensive?
