Check this hotlap: lap 1, time: 1:05.00, T6. I think this tyre barrier bypassing in the chickane should cause HLVC-invalid hotlap but it doesn't. I tried that many times after that and it seems not to be a contingent.
Bug I found: Whenever you pit during hotlapping, it says hotlap invalid (wall) even though the car doesn't touch anything. Minor, just wanted to contribute...
