the answer is friction
A car can roll over when there's something slippery on the road like gasoline or ice and snow.
Letting gravity roll the car along... as on a hill or gradient.... and with the engine off or the gears in neutral.
To keep the car engine from over heating
to roll over is 'retourner' in French. When speaking of a road accident where a car rolled over, you "se retourner" or "faire un tonneau".
The roll cage is around the driver, to prevent the roof from collapsing during a roll over crash, and injuring or killing the driver.
If the tracker is a "standard shift" not automatic transmission. You could pop start the engine by putting the car in 1st gear, with the clutch pedal down and the ignition on. Roll the car and once car is rolling release clutch pedal. Vehicle should start, hope this is what you ment by "manually".
A car used for racing has a higher than normal chance of being involved in an accident and is likely to actually roll over. A roll bar is a fitment inside the car of a strong framework, which prevents the car bodywork collapsing and therefore protects the driver from injury.
Used car, NO. New car, possibly if it qualifies under your state's lemon law.
It will not turn over.
It has over 10,000 parts!
A car rolls over from an imbalance of inertia and grip. It would take several degrees to fully understand it. For the average Joe, its when the majority of the load in over to one side of the center of gravity of the car, and then the inertia of the car forces it to keep tilting until it is stopped. But usually, car's don't roll over. Top heavy transports like tractor trailers and SUV's have a better chance of rolling over, because they have more mass to shift over the center of gravity. Hope this helps
