Now I know it’s called Phantom or Ghost Breaking. When in cruise control or in autopilot, in certain highway areas from 65 or 70, it breaks down to 25 mph. Cars behind gets dangerously close, as well as the royal scare face I get! There has been two major updates since I bought it, and it still ds the same. Since, more or less, I know the highway spots where it happens, I’m ready for it. However, when traveling elsewhere I’m not that lucky. At those high speeds it cam potential cause harm or even death!
