We still haven't released details on how the rollover predictability ratings will be conducted but that is imminent. It's part of our consumer safety information program that will be expanding to eventually include brake and lighting performance.

We've looked at a number of different alternatives and ways to measure rollover predictability. There are rollovers you can create on the test track and there are mathematical formulas. We're still trying to see if one is more accurate than the other and then we'll decide which is fairest to use.

Our researchers are working out a ranking system now. This is an important category, though, if you do a lot of night driving or if your vision is starting to diminish.
