Still waiting for the Ford, but on my Model S and Model Y, I can see when the break lights turn on in the car visualization on the screen. The break lights will not come on when you only slightly lift your foot off the accelerator, but will come on when your speed decreases from 70 to under 65, for example. But not from 70 to 68, 67 approximately. I’m also curious how it will work on the Ford.
