>Unnecessarily harsh. I reckon it'd be better for everybody if I didn't crash at that speed.

No. You are not a professional driver, or even a good driver, because a good driver would recognize that the proper place to do 250 is on a race track. You make the road dangerous both for you, but even more so for other drivers and will, one day, kill someone. So, please, kindly fuck off of french roads, whether it is through crossing the border and letting it be someone else's problem, or eating a tree like half of the dumbasses driving polish rental Audis.
