I assume that most U.S. i3 owners specified the Parking Assist option mainly to get the backup camera. The camera is now required by U.S. law, so removing it from Parking Assist didn't leave much of value. Automatic parking is slow and can easily drag a wheel along the curb.
The Parking Assist option also included front ultrasonic distance sensors. These must now be the S508: Parking Distance option. Is this standard in North American i3's?
