Hey I'm not saying its right, my brother just got caught doing 50 in a 40 and I just told him to accept it and get on with it.
Just trying to point out that 30s and 40s are very different and some 40s are ridiculous
72 in a 40 is excessive though so if I was your mate I wouldn't try and fight it, will make him look even more irresponsible if he does
