I think you might be talking about a backwards roll which is basically a roll from crouching where you lean backwards onto your shoulder and your arms are straightened, and you end up standing.
the car will probably roll backwards or forwards if it is on a hill. If the car is on a flat area of the ground, nothing.
because they roll easily...
Your probably letting your transmission roll forward or backwards after you put it into park. This puts pressure on the transmission where it stops and it "pops" out of park for this reason, making the loud noise. Apply the E-Brake after putting it into park but before you let off the regular break, it wontcontinue to roll.
Yes, it can.
if the wind is powerful enough it can make a biker roll backwards.
If the handbrake isn't on and something is pushing it backwards (gravity, another car, etc.) then yes. Cars don't roll on their own.
In a rollover situation, the Jeep. It has a roll bar where the Tahoe does not.
depends how you drive it
You may have a U joint that is going bad if the roll is just a few inches. If the problem is rolling a fairly long distance or continuous, your emergency brake is shot. You need to get the lines adjusted.AnswerTurn your wheels out towards the street,that way the tire will rest against the curb and it will not roll.
Because, it can roll down a hill or you put it in reverse.
You need a transmission or gear shifter repair. The only reason for it to roll is that it is not actually engaged in the park position.
