I'm of the opinion - You're all kidding yourselves if you think 1, 2 or no roll bars is comparatively safer to the alternative.
When you're number is up, it's UP!
I'm with RodKnock... How many of you 2 roll bar preachers wear helmets when driving your cobras, or better still, have your passengers wear helmets?
Do you guys ride bikes? Or how about take a pillion on your motorcycles?
Better go back inside and wrap yourselves in cotton wool.
Puhleeese... whatever helps you all sleep well at night.
FWIW: I've two roll-bars... One on the car, and the other brand new wrapped in plastic, sitting in storage.
I've 2 reasons for this:
1) Cos I cant bring myself to put holes in the aluminium
&
2) just b/c to my eye, there's seemingly a beauty and "balance" in the subtle asymmetry caused with 1 roll bar sitting over the drivers side steering wheel. Just the same as there is a beauty in "subtle" asymmetries in the banks of an FE engine (Fuel log side vs linkage side and Overflow tank and distributor side), and in the faces of beautiful people.
Ughhhh - Now I'm need of a shower for posting in this thread!
I feel so dirty
