The Chevy Bolt has it's brake lights come on automatically regardless of what is causing the deceleration, and I believe Hyundai is coming out with an OTA fix for that as well.
When you drive the electric car every day, it's nice using the one-pedal mode... Except it has taught me a large flaw in that my instant braking reaction is to depress the regen paddle, which doesn't work (only 10kW of effort) when the car batteries are well below -20 C, causing me to panic and brake too hard using the traditional hydraulic brakes.
