Proximity radar inaccuracy

Is it just me or is the vehicle radar off? Passing a slower car as an example. Radar will show I'm fully passed an AI car, single player race. I look to my side and their nose is still alongside my rear quarter. Not until there's maybe a quarter of a car gap between my vehicle on the radar and the one I am passing am ai actually just barely past them. The gap I've watched increasing being complete bullshit.

Makes it frustrating as heck to trust the radar, believing I'm past and clear only to get rammed by the AI that's still alongside me.

I could understand some latency if it was in an online race. Maybe forgive a little. But in a single player race it should be perfect or it should err on the side of caution. Showing clear and past when I'm not seems pretty terrible to me.
