Ah shoot, when I saw "fixed a ramp" I got my hopes up. If anything, I would love if an in-game timer was available. It's annoying bc I have to go and open up my video editing software every time I think I get a PB. Below are the current timing rules. Thanks for reading my comment btw :)
time starts as soon as the loading screen ends and "Find your car" appears in the UI.
time ends as soon as the car rusts and "DIE" appears in the UI.
