Daily Driver Roll Cage, comfort?

Younggun - you are right that there are risks, but saying they are lethal is overstatement. The cage needs to be properly padded in impact areas (is is a requirement for CAMS rollcage certification in Australia), but if the cage is set high in the cabin and the seat and harness are properly adjusted, the risk is minimised. In a 700hp Hemi Dart, I would certainly trade the chance of a head-knock for the enormous protection afforded by a good six point cage.
