yeah, fuck air bags. i disabled mine in my civics/del sol.
a proper harness/cage system would make the need for air bags null and void..
I just can't fathom that's its actually ILLEGAL to drive with a helmet on in a car in some states.
That said, my crew have done it. trips to vermont, E, wildbill, and myself all had our helments on for the majority of the 'spirited' ride up. They've also been known to be worn in the NW corner when we're doing some backroad bombs.
Heightened driving awareness, less background/wind noise, and if anything goes wrong, having the helmet on will certainly help prevent any head injuries.
