One pedal driving in electric vehicles reminds me of engine braking on motorcycles, which is much more effective than engine braking on ICE-powered cars.

The issue of the brake light not turning on when using the braking functionality, which can result in getting rear-ended, also reminds me of how #motorcycle riders often get rear-ended when engine braking without also at least turning on the brake lights.

The motorcycle case is why I usually at least lightly apply the friction brakes when engine braking, unless it's to maintain speed when going down a steep hill.
