Road America is a fantastic circuit, I'd love to see F1 cars trace on it too.

Growing up playing football we were discouraged from taping ankles and wrists because in a bad hit you're then likely to blow a knee or elbow because the leading joint has no flexibility. When you have everything external tied down, the only place for energy to go is internal organs.Jolle wrote: ↑Tue Jun 25, 2019 4:47 pmI guess, if you want to prevent neck injuries, you somehow have to limit the motion of the head when you crash. In "the good old days" without any head protection at the sides (the headrest) or to the front (HANS) I can imagine the force to have a neck injury is a lower then without a helmet. But... now we have all the restraints around the head, wearing a helmet allows for much higher forces because the helmet/head is immobilised.
On motorbike accidents most neck injuries happen when you hit your head on something and your body is the dead-weight, not your head. Without a helmet, almost any major accident is quite soon fatal because your skull isn't very well build do deal with curbs, poles and falling on from a bit of distance.
You see this with many safety devices. There is almost an order of injury and solution. Before helmets were common sense, most bikers would die from head injuries, but when they started to wear helmets suddenly broken necks and backs were becoming the main injury. And now with good back protectors and neck protection systems (as used in Dakar for instance), we see most of the major trauma is internal bleedings and broken legs/arms.
Sound a bit like the 2009 KERS F1 unit, but even less power. The idea driving full electric trough the pit lane will need some extra clutches...Morteza wrote: ↑Thu Aug 01, 2019 4:04 pmhttps://twitter.com/RACERmag/status/1156943065166286853
Not if they direct drive the input shaft (the driven shaft of the gearbox i.e. the one without any dogs, coaxial to the crankshaft). Open clutch, gear engaged, MGUK powers the input shaft and thus the rear wheels. To use as a starter motor, engage neutral, engage clutch, and drive the input shaft with the K.Jolle wrote: ↑Thu Aug 01, 2019 5:09 pmSound a bit like the 2009 KERS F1 unit, but even less power.
