Wow guys...Can't we all just get along?
I am of the opinion drivers should sit in a glass bubble, right out in front of any type of vehicle. I reckon accident numbers would then drop a lot.
Trouble is, drivers don't see themselves a vulnerable when piloting a Hummer or other large bolide.
I had occasion to sell my 1962 VW Crew Cab after a near miss. I sat contemplating how much protection was afforded by the 1/32nd thick front panels. I concluded my knees are worthy of better protection.
