Yes, Auto emergency braking system disengage without notice, No, No, No

The center console gear shift has a lever to disengage the current gear to shift into another gear. However, if the lever isn’t fully pressed, the gear shift will still move, but the car remains in the original gear. So a driver may believe the shifted from reverse to drive (or vice versa) when it hasn’t. In theory, this lever should work like a manual transmission. One cannot shift gears in a manual without engaging the clutch fully. The automatic transmission/gear shift lever should work the same. In other words, the gear shift should not move/disengage unless the lever is fully pressed. Note: the vehicle (a former loaner vehicle) was recently purchased.
