I'm wondering if anyone else has experienced this. I was at a Nissan dealer and they were going to let me charge on their J1772 for a while. There was an electronically-controlled gate, which they opened for me, and I was going to back up through this (very wide) road to the charger location. The gate was completely open (vertical). When I tried to back up the MS past this point, the MS would halt and not go past the gate's location. I didn't see any vehicles or obstacles close by that I thought would trigger any collision avoidance; there was no warning message or chime - the MS just would come to an abrupt halt when I tried to back through this point. After 3 tries, I had to turn the car around and go thru it going forward. No problem. The only thing else I can add was that there was an in-ground sensor, so that the gate would open for cars coming out of the parking lot. I don't know what sensor in the back of the car would somehow react to this. Has anyone else noticed this odd behavior?
