When automakers first came out with cruise control, it was a real luxury item.  The older cruise controls used a mechanical vacuum system but it worked.  Well, some of the time.  Now days, cruise control is all electronic, thanks to computers.  It's reliable and a real convenience on long trips.  Cruise control is offered on most vehicles and standard on a lot of them.  Because it's electronic, when it breaks, it's usually some electronic component.  Your vehicle's cruise can be the victim of a blown fuse. Or your vehicle's speed sensor, which—not surprisingly—measures your vehicle's speed, can also stop working.  And that will cause your cruise to stop cruising.  Vehicles with cruise control also have a built-in feature that, when the brakes are applied, turns off the cruise.  With electronic cruise control, that happens thanks to the brake pedal switch, and if a problem develops in that switch, the cruise might not work.

Recently, Nissan introduced the latest version of its Leaf, the company's electric car. It has many new features, including something called e-Pedal. It allows the driver to let up on the accelerator and, unlike a gasoline engine car, the Leaf doesn't just slowly lose speed; letting off the throttle pedal brakes the car in a very controlled way, using regenerative and sometimes friction brakes. With practice, a driver can go for a fairly long time without touching the brake pedal. Another system, similar to those found in self-driving vehicles, can steer the car to keep it in the center of the lane using a camera and radar. It literally watches the lane markers and, of course, doesn't work well in snow that obliterates those markers. But the technology is impressive and can greatly reduce fatigue on long trips. In fact, much of this technology has "trickled down" from research on autonomous vehicles, such as adaptive cruise control that slows down your vehicle (even to a stop) if the v ... read more
