Editing Stiction (section)

==Automobiles==
Stiction is also the same threshold at which a rolling object would begin to slide over a surface rather than rolling at the expected rate (and in the case of a wheel, in the expected direction). In this case, it is called "rolling friction" or ''μ''<sub>r</sub>.

This is why driver training courses teach that, if a car begins to slide sideways, the driver should avoid braking and instead try to steer in the same direction as the slide. This gives the wheels a chance to regain static contact by rolling, which gives the driver some control again. Similarly, when trying to accelerate rapidly (particularly from a standing start) an overenthusiastic driver may "squeal" the driving wheels, but this impressive display of noise and smoke is less effective than maintaining static contact with the road. Many [[stunt]]-driving techniques (such as [[Drifting (motorsport)|drifting]]) are done by deliberately breaking and/or regaining this rolling friction.

A car on a slippery surface can slide a long way with little control over orientation if the driver "locks" the wheels in stationary positions by pressing hard on the brakes. [[Anti-lock braking system]]s use wheel speed sensors and vehicle speed sensors to determine if any of the wheels have stopped turning. The ABS module then briefly releases pressure to any wheel that is spinning too slowly to not be slipping, to allow the road surface to begin turning the wheel freely again. Anti-lock brakes can be much more effective than [[cadence braking]], which is essentially a manual technique for doing the same thing.
