The predecessor of modern electronic traction control systems can be found in high-torque, high-power rear-wheel-drive cars as a limited slip differential.A limited-slip differential is a purely mechanical system that transfers a relatively small amount of power to the non-slipping wheel, while still allowing some wheel spin to occur.
The computer control system needs the front drive shaft to turn, so that it can monitor and compare the rotational speed of both the front and rear drive shafts. If the rear drive shaft starts to turn faster than the front, the system interprets that (along with input from other sensors) as traction loss.
ESC can function on any surface, from dry pavement to frozen lakes. [30] [31] It reacts to and corrects skidding much faster and more effectively than the typical human driver, often before the driver is even aware of any imminent loss of control. [32]
Upwind: the rotor harvests power from the oncoming air and drives the wheels, as would a wind turbine. Downwind: when the vehicle is traveling faster than the windspeed, the ground is the fastest-moving medium relative to the vehicle, so the wheels harvest the power and impart it to the rotor, which propels the vehicle.

Pass another vehicle that is slowing or stopped on the main traveled portion of the highway, disabled or preparing to make a left turn. Allow another vehicle traveling faster to pass.
Adaptive cruise control does not provide full autonomy: the system only provides some help to the driver, but does not drive the car by itself. [3] For example, the driver is able to set the cruise control to 55mph, if the car while traveling that speed catches up to another vehicle going only 45mph, the ACC will cause the car to automatically brake and maintain a safe distance behind the ...
Turn signals are activated by the driver to alert other drivers of their intent to turn or change lanes. [12] While the modern turn signal was patented in 1938, [13] electric turn-signal lights date back to 1907. [14] As of 2013, most countries require turn signals to be included on all vehicles driven on public roadways. The turn signal lever ...
