    Driving the 'Ring was much different back in the day. Apparantly seatbelts were optional...

    Yeah...no kidding. Fairly certain they did not have rollover protection.

    Wow, I'm stunned by the pure number of rollovers back then. People nowadays are complaining that cars are getting too heavy. Well, if today's small cars were that light, they'd be right there along with the 70's cars, rolling on away.

    I did notice none of the Porkers rolled over though. Good job Porsche!

    It's not the car you drive, it's how you drive it.

    I don't think it has as much to do with weight as it does center of gravity, BP.

    The cars that are constantly going over all have high CGs. Same reason SUVs are always rolling over despite weight.

    The Porsches in the vid are all low CG relatively speaking.

    Physics lesson of the day: in order to have a rollover, you need to have your Center of Gravity be higher than your center of force. Center of force would be just averaged, and since we are expecting the car to roll over sideways and not do a front or backflip, the axis we single out this axis and only look at the car in one dimension. As soon as the center of force is lower than center of gravity, we start getting wheels raising, if it goes over enough you get rollover.

    Right, but modern cars (that aren't SUVs or Minivans) that are heavier have a lower center of gravity as well. You won't see a modern car flip nearly as easily as one of those older cars. Safety is the key here; it's heavier and also has a lower center of gravity so it doesn't run the risk of flipping as easily due to the extra weight.

    Weight in itself has zero bearing, BP.

    Only where the weight is placed matters.

    If a car is heavier and the weight is higher up, it will be more likely to flip over than a lighter car, not less.
