Well, the S has side sensors in that they claim it has "360 degrees of ultrasonic sensor." Not that in-the-door sensor, but it does already detect the side. The big question is how integral is the new door sensor to this new collision avoidance. Either way, not a huge difference. But it would be a nice incremental sensor on the S if it's used for more than door height.
The discussion of those sensors was completely in the context of door height sensing. However, that doesn't preclude multiple uses.
