I love that RX7 vid, a classic. The bloke putting his foot on the dash is awesome.
Thing is, people who go off make clear mistakes. The RX7 vid is one of the best "how not do Paddock Hill" demonstrations out there. Why on earth would go round the outside edge of any corner, let alone Paddock?
The Fiesta video is easy to explain too. The first one, on 'cold tyres' had turned in too early and realised he was going to take the kerb. Decided he didn't wanted to, lifted off, and almost spun. If he just ran over the outside kerb, he would have been fine.
The second red Fiesta completely missed the apex, realised he was understeering off and so lifted off. Bye-bye Fiesta.
No one needs to be scared of Paddock, it is easy. It's also a great fun so shouldn't be missed out... i would say the 'Ring is far more intimidating!
