I don't have a Lightning yet. This does define one of the most frustrating things about driving ID.4. I hate following traffic thinking I'm a nervous douche brake checking everybody when I lift off the pedal. I don't want to be plowed into, either. There are defined parameters using the vehicle's decelerometer, but they are hard to figure out without knowing when the brake lights are triggered. Makes me wish for those weird fiber optic light indicators on cars in the 80s. A tiny brake light display in the cluster would be great.
