I just found this YouTube video by NeroBax that shows how much tyre wear the option Avoid High Risk Kerbs saves. And the results are insane. It looks like there's over 50% tyre wear saved just from avoiding high risk kerbs, at a very minimal lap time loss. I'm fairly certain this needs to be rebalanced.
