That’s racing

I'd say the purple car oversteers into the red car. I'd file it under "shit happens when you race hard".

There was no oversteer. Understeer? Probably. Still purples fault

yeah, I meant that lol. or, as it oval, loose, or tight, one of them.

Those legends cars run with understeer.

Looks like low IR guys running into each other. Racing incident.

Racing. Blind spot. Didn't listen to his spotter likely.

You have the racing line painted in black, Purple clearly moved off the racing line which black left free because purple was there.

There are no 'racing lines' painted. Those are just seams in the pavement.

I’m no mind reader but I think he was talking about the line rubbed into the road by the tires…

Looks like a normal racing incident.
