saw a segment on the news about the 2012 requirent for vehicles to have anti-rollover potection. The technology uses braking and steering control to reduce the chance of rollover. do you think this will kill autocrossing?

I can see this happening on trucks, vans, and SUV's, but you have to hit a ramp or something to flip most cars and rollover protection can't anticipate that. This legislation at least makes more sense than mandatory tire pressure monitors. My biggest question is what is the vehicle going to do to stop the roll over? I'm not sure I would want a vehicle to correctively steer for me in any situation. I can imagine steering to avoid an accident and the computer senses to many instant G's and steers me back into the accident. Applying the brakes on the loaded wheels would be OK and might prevent a roll over.

My mom had a Ford Bronco II which is the vehicle that is rated one of the (if not the) worst in roll over . I drove it a few times and yes I could get it to lift a wheel easily (which for crap street tires is scary), but you still had to try to roll it, have bad shocks (probably why most rolled over), or hit something to roll it. I truly believe that if I braked, snapped the steering wheel hard one way while going over 50mph that I could have rolled it, but my moms did have bad shocks. But I don't think I could roll a Camaro unless I hit something, which again no computer can account for.

only thing i see is that with active suspension, they can try and minimize some body roll that is becoming dangerous... especially on high center of gravity cars.
Apart from that... the only thing that can offer good roll-over protection is having a more rigid cage (frame) over the head as well as better seatbelts... heck, I'd wear a 5pt everyday. As for convertibles, i think they'll legislate the hoops or at least the hoops that pop out in case of a rollover.
