Long story short: I made a car in automation that handles questionably despite my best efforts not to. The one characteristic I'm talking about is its' tendency to oversteer dramatically under heavy trail braking. And I have no clue why that happens. Rear brakes are significantly smaller than front ones, braking distribution is waaaay up front, rear sway bar is relatively soft and this little mofo still decides to play tricks on me. I attach zipped .car file, if anyone has some spare time please take a look at it, or drop some suggestions under this post.
