Get someone to video your rear tyres during braking, Rob. I am DAMNED if I can see my OWN rear tyres while braking!
Let's be certain, here... I am NOT saying that ANY good driver locks-up his tyre for more than a FRACTION of a second. The point I am denying is that we have the skill or ABILITY to maintain a tyre rotating at some substantial FRACTION of the 'rolling' speed (i.e., rolling smoothly forward at 80% of the front tyre's rolling speed).
When we brake hard.... we pass though MANY stages ranging from 'rolling' to 'locked' and we do it REPEATEDLY simply by letting the radpidly changing grip of the track's surface control that rate. I suppose I mean something like an angler's slipping-real; when the fish tugs hard.... it slips.... when it doesn't tug as hard... it grips!
Liam is doubting that ONE of those stages includes locking-up. He sees that as a MASSIVELY different concept to rotating the wheel at (for example) 50% of the speed that it would 'choose' to roll if we released the brakes!
