i've been up there this year running past 100, my mate was up there in quite a noticeable car running well past 100 and he got no bother,
tbh on a big day like sunday I wouldn;t risk it and if u have one I would take it,
I just borrowed my mates bike helmet again, atleast I'll have one if I do get collared about it...... thats if I dont blow mine on the rollers on sat
