That was my point, Liam..... you DON'T know that locked-up tyres don't work in a VERY short 'exposure'. The example of reversing at 5 kph while traveling at 15kph makes the point! From the 'contact point's' point-of-view....the 'contact point' it is performaing IDENTICALLY to the 'gold standard' of being slowed by 20% while at 100kph......

What we ALL know is that letting a tyre SLIDE along the SAME contact patch for a long period WILL give a poor performance. I still havent' seen any data on 'instantaneous' lock-ups!

We also know: a contact patch that is doing EVERYTHING IDENTICALLY to a locked wheel but still 'exchanging' the contact patch for a 'new' one at a 'good rate' WILL produce good braking. Because that's EXACTLY what the 'gold standard' is doing. And that was EXACTLY what I claimed we do in karting. We just do it in short, jerky 'frames' whereas the 'gold standard' would be a smooth continuum.

If you can tell me how the contact patch can KNOW what's happening to the rest of the vehicle at 100kph, 120kph, 300ph and 15mph (while reversing).... then I'll be able to accept your point....

I just CAN'T see how it 'knows'.
