How do you drive a car with one-pedal driving?

Why do some cars offer one-pedal driving?

Cars that offer one-pedal driving as an option are a relatively new phenomenon. Why do some cars offer one-pedal driving and how does it work? Using it is actually quite simple, you just let off the accelerator and the car begins slowing automatically right down to a gentle stop. Why this is and how it works is a little more complicated.

For now, and likely in the future, only electric cars offer one-pedal driving. This is because electric cars have a built-in brake with their motor. To be fair, so do gas-powered cars, but it offers little advantages outside of excess engine wear.

When you spin an electric motor without applying current to it, it will actually create electricity while producing drag. That drag can be put to work slowing the car and that energy can be put back into the batteries in a process known as regenerative braking. When one-pedal driving is in use, simply letting off the accelerator engages this braking effect to maximize the range of your battery. Most one-pedal cars also let you decide how aggressive this braking should be.

Don’t worry, if your car offers one-pedal driving, then it can still be driven normally with two pedals. In fact, all one-pedal cars still include two pedals. One-pedal driving is just an option that’s provided which can improve your regenerative braking and also reduce wear and tear on your brakes.

As we mentioned above, all cars that offer one-pedal driving, still have two pedals. This isn’t just so that you will have the option to drive with two pedals. Letting off the accelerator in a one-pedal set-up typically only applies regenerative braking. There is a maximum amount of braking force that can be applied to your wheels in this manner, and it is not enough to stop in emergency situations.

This is why the brake pedal is still necessary to have. In an emergency, you will still want a pedal you can step on to bring your vehicle to a halt in a hurry. Though it is possible to create an accelerator pedal that would apply maximum braking force when letting off entirely, this would likely lead to more accidents. In short, though there may be a future that has cars with no pedals thanks to autonomous driving, there likely isn’t a future where cars actually have only one pedal.
