I have been driving my hybrid under the assumption that my brake lights triggered when ever the car used regenerative braking. Guess I will have to be more careful.

If you're not driving a Hyundai, it's probably working as you expect.

  I'm driving a Honda. I looked it up and people online say that it has the same issue. However, I plan to observe for myself.

    Now I'm curious about my Volvo. I do most of my freeway driving with the adaptive cruise control adjusting my speed to match the flow of traffic. I have no idea if my brake lights are triggering when the ACC slows my vehicle due to a slower car in front of me. I certainly am not touching the brake, unless I need to stop more quickly. Given Volvo's reputation for safety, I'm assuming they got it right but that is purely assumption on my part.

      My guess is that most decent TACC implementations won't activate the brake lights when slowing for a car in front, unless that car cuts you off. Generally the deceleration should be slow enough that it falls under 'engine braking' levels and therefore unworthy of a brake light.

  Update: My Honda does not show brakelights until I hit the brake peddle, even on the highest regenerative breaking setting.

Have someone drive behind you and ask them if your brake lights come on during regen braking, or do what TC did and attach a camera to the back of your car. Based on other comments in this thread, your hybrid probably triggers the brake lights during regen braking. It seems only Hyundai got it wrong.

  Driving a Volvo BEV, they got it right. One pedal driving + slight regen doesn't light it up but anything harder where you can feel the deacceleration in your seat, the brake lights illuminate. I haven't driven a lot of other EVs but Volvo put a lot of thought into their one-pedal mode and it's fantastic. It's incredibly precise.
