In a scenario where you can magically "un-park" with your phone, what is the point of checking whether nearby cars offer a similar parking feature? There is none. Hence, redundant.
You seem to have misunderstood that a bit. The car checks if other cars support the feature before it tired to park in a tight spot - not after!
Scenario 1:
Auto-parking car arrives to a parking lot and notices the parking spot is too tight.
Asks cars around if they support the feature. No answer.
Auto-parking car will not park here, because it would prevent the other drivers from entering their normal cars.
Scenario 2:
Auto-parking car arrives to a parking lot and notices the parking spot is too tight.
Asks cars around if they support the feature. Both answer yes.
Auto-parking car will park here, because the other cars can get out using the auto-park feature.
Scenario 3:
Auto-parking car is parked in a tight spot. Car on the left leaves. A normal car approaches, but the driver notices that the spot is too tight, so he decides not to park here, because he won't be able to open the doors on the right.
Scenario 4:
Auto-parking car is parked in a tight spot. Car on the left leaves. An auto-parking car approaches, asks cars around if they support auto-parking feature. Both answer yes. Everyone can still get out because they have the auto-parking feature.
Did I miss anything?
Your spot is tight, theirs doesn't neccesarily have to be. You auto park between two auto parking cars with barely a centimeter on both sides. Then the auto parking car to the left of your tight spot leaves and is replaced by a usual car. There is plenty of space to its left, so that driver has no problem getting out. In this way your check for whether the surrounding cars have a feature is pointless. Kind of reminds me of checking for enough disk space before you write to a file -- equally pointless.
Yes, so what? You come back and press a button on your phone "Un-park" and your can will come out of the tight spot. What is your point?
So you can expect to come back to the car park and find your car boxed in by one of these parked each side six inches from your car.
Have you thought that the car would try to wirelessly communicate with the nearby cars to see if they support a similar parking feature and only park in a tight spot if they reply YES?
Because, as we all know, these exact cars will stay there until *we* decide to leave and will never be replaced by other cars.
And your point is? If the other car doesn't support the auto parking feature, then the driver probably would not park in that tight spot, because they wouldn't be able to get out of their car...?
1) You still need to squeeze back into the car when you're ready to leave (assuming there is no "unpark" feature)
2) What are the odds that the driver of the car parked NEXT to your in your overly narrow space will ding your passenger side door trying to get into HIS car?
I am sure Ford engineers haven't thought about this. They couldn't have come up with ideas like (1.) the car getting out of the parking spot the same way it came in (with a press of a button on the user's smartphone), or (2.) wirelessly communicating with the nearby parked cars to see if they support this parking feature, and only squeeze into the tight spot if they reply YES.
