The bolt ev has a dangerous design problem when using regenerative braking. you don't have to use the brake pedal to slow or stop. the car slows in relation to how quickly you release the accelerator pedal. the brake light only comes on when the accelerator pedal is fully released. the car will stop quickly at that point with the brake lights on during the last few seconds until at a full stop, when the brake lights turn off. the vehicle remains at a full stop without any brake lights on once your foot is off the accelerator. when stopped you have to hold the brake pedal to keep brake lights on to warn following cars. this needs to be addressed to give adequate notice of changes in speed to following drivers to avoid collisions.
