Tilting car
A tilting car is a type of automobile that has the ability to change the angle between the road and the bottom of the passenger cabin in a way that allows it to avoid rolling over while the vehicle is driving through a curve. Tilting is critically important for narrow-track vehicles because unlike wider vehicles, the acceleration required to make a non-tilting narrow vehicle skid during a curve is less than that required to make it roll over; tilting allows narrow-track vehicles to "lean into the curve".
