I experimented with a faster more sweeping line through the old Riches chicane at an Snetterton sprint event in the late '80s. Would have been a lot less damage if I'd just hit the tyre wall rather than roll the car trying to correct a lurid slide. When they go, they go, I momentarily lost conciousness during this happening but from the damage, it must have gone all the way round at least once. I came to in the upside down car with my crash helmet trapped between the bootlid and the tarmac; the petrol breather hose had set up a siphon effect as the car went round. so 4 the star running down my back didn't feel good. Fortunately, the marshals were quick to right the car and get me out.
The scrutineer made a big deal of removing the 'approved for motorsport' sticker from my crash helmet, perhaps he though I was going to patch it up with some bondo and give it a quick respray.
BTW, if you are in a rollover in an open car, resist the temptation to put your hand out to hold the car up. I only got a broken wrist, a mate broke both arms when he rolled his Sprite at a speed hillclimb.
Obviously, I mended the car, but it was quite a few years before I managed to find a replacement 'Bluemels Brooklands' steering wheel rim, so I had a tactile reminder of the potential dangers of speed in the big flat ground into the outside edge of the 'old' rim.
