Oversteer… it looks great in car commercials when the back-end of a car is skidding sideways on a shiny surface where there are no obstacles around. But it’s not so good for ordinary drivers! Oversteer occurs when the rear tires of a car lose their grip on the road when heading into a turn. When that happens, the back end skids out. To avoid this and the serious damage it can cause, you should approach turns slowly and cautiously, especially in the rain.
