Oftentimes you drive and se a car that rolled over, just one car.. how.. why?.. here is how and why:

How your car can roll over without any much help from any other car and without any sudden manouvers!

[b]A single-vehicle rollover is usually not caused by a steering maneuver. Instead, the vehicle usually has to "trip" on something, such as when it swerves into a curb, pothole, or a soft roadside shoulder. The government has estimated that 95 percent of rollovers result from trips. Some observers say that number is too high. If a vehicle leans in such a way that a tire's sidewall deforms and the wheel rim strikes the pavement and provokes a tip-up, then the government counts that as a tripped rollover.[/b]

Given the right circumstances, any vehicle can roll over. However, taller, narrower vehicles such as 
SUVs, pickups, and vans are more susceptible than traditional cars are because they have a higher center of gravity and thus are more top-heavy. [b]Sideways forces that develop when a vehicle rounds a curve shifts the center of gravity to one side, which can have a dramatic effect on the vehicle's balance. [/b]The lateral forces increase with speed and also with rapid changes of direction--for example, when a driver makes too sharp a turn one way and then overcorrects the other way. Those transitions can set up a pendulum effect, with larger and larger swings and an eventual loss of control.

But Consumer Reports encountered that very phenomenon a few times during its emergency-handling tests of SUVs in the 1980s and 1990s. We consider those tip-ups to be untripped, because the vehicle essentially fell over itself on a flat surface without encountering some obstruction. The distinction is important because the supposed rarity of untripped rollovers has served as an excuse for the government and the auto industry to play down rollover risk and put the blame on the driver and road conditions rather than on the vehicle.
