- I agree about the effect of the steering column... they are specifically
- designed to absorb impact, and the driver also has something to brace
- him/herself against, which tends to keep your head from hitting anything
- (an argument for driving with both hands on the wheel?).
-
- Good start... I'd follow up by saying you should have a
- five-point harness (submarine under THAT), dual airbags, PROPER
- protection from side impacts (air bags don't cover this right now), and
- a well-engineered roll cage area for the passengers. Another point; I don't
- know if helmets are all that great an idea if you don't adjust your
- headrest properly!!! If this is overlooked, the added weight from the
- helmet will only serve to multiply the effects of head/neck injuries.
- People don't want to wear a helmet in their car anyway (although it
- obviously helps).
-
- Usually, if the car's structure and restraints are properly designed,
- and the equipment is adjusted correctly for the person using it, air bags
- become a moot point (note racing designs). But what the heck, your
- buttshield can never be too thick :).

-
- I agree, rear passengers tend to become projectiles in head-on/rear-end
- collisions. Once again, give them a five-point harness and a well-adjusted
- headrest and MAKE THEM USE IT. As for pets in cars, they should be in a
- pet cage that is belted into the seat... if there is a better way to do
- it, I would like to know, because even then the pet gets tossed about
- in the cage during the crash.
