Howard-I was at the last v8 Supercar race at Oran Park.Right in front of me on the last corner, an ex Bob Jane Escort rolled and hit the wall while in mid air at full speed..The passenger side and roof was flattened to the floor. The alloy rollcage had bent and broken completely. Absolutely no strength at all.YET the authorities in Aus dont want to compromise the historical value of the car by changing the cage-totally crazy.A roll cage is not a roll over cage, it is the only thing that surrounds you and protects you.And dont get me started about those using exhaust tubing in the early 70s..............
