In my tests, when cuts like those happened, it gained at most 3 tenths of a second for major ones. More minor barely illegal ones gained a tenth if that. A 90 second penalty for what would have been at most 5/6 seconds gain does seem a bit too much. If you watch the replay, most of my time was gained through the Lesmos. That is where I managed to find the time to break the draft.
Granted I don't think I shouldn't get any penalty, but seeing as a cut gives you such a 3 second penalty, and that most people had a lot of cuts, the results now depend on who managed to get round the race with the fewest number of mistakes which seems a bit stupid. And to be fair, I'm not here to spend almost an hour going around the track driving safe to get a moral victory. I'm a racing driver, I'm mean't to attack the track, not tip-toe around it. As for the people saying it gives better tyre wear, it doesn't because although the "angle might be less" which it barely is, if you take more speed, you will use the tyres more. So slight cuts like that one make tyre wear worse.
I know I said I didn't mind a penalty, but 90 seconds is going too far IMO.
