2013 Tesla Model S: Brake Light Actuation

March 05, 2013

2013 Tesla Model S

Our long-term Tesla Model S has a pretty aggressive regenerative braking system. When you hop off the accelerator pedal, the deceleration is as strong as easing into the brakes. It takes a little getting used to, but with smooth inputs, you won't be getting your passengers carsick. But the sharp deceleration had me a bit nervous about getting rear-ended.

Thankfully, the brake lights do indeed turn on when there's enough deceleration, whether or not you're foot is on the brake pedal. If you ease off the accelerator and slow down as a normal gasoline-powered car would, the brake lights stay off. So at least the driver behind you can't blame the Tesla when they're distracted by their phone, nav, dog or latte.

    When did you guys get this bit of automotive vaporware?

    It's not vaporware if it actually exists and can be bought.

    YOU'RE foot??!? Surely you mean, "you're A foot"? ;-)

    Is there a way to adjust the degree of deceleration, using the fancy touch screen? Surely, there must be.

    There are two setting. Standard (described in article) and Low, which seems to mean about as much decel as an automatic transmission - very little.

    The Roadster regen is even stronger. Both Teslas use an accelerometer to activate brake lights.
