Oh, I should have mentioned that the elderly couple was trying to turn into their driveway. They lived right on Rt.47. Their house was maybe 30 feet from the road, if that. It would really suck for a quick, 5-minute trip to the Pantry 1 to turn into an hour-long ordeal if you had the misfortune to find yourself with a sudden, urgent need for milk on a Saturday between Memorial and Labor Days.

Nor is there a need to- since you're not blindly backing out 90 degrees into cross-traffic.
You're back out 45 degrees into one-way traffic- easily handled by the current rear camera stuff.

Even if allowed, backing in is a bad idea in many cases because you can't load stuff in the trunk if there is a divider or other cars.

You just can't satisfy everyone...
I've been told for years that backing into a parking spot is the correct way, because it is safer.... USA Fire Protection Blog

It's not about "satisfying" anyone. It's about the fact that a fully autonomous car will have to be able to deal with this situation.

Except, it won't, because it'll just back into 90 degree spots, and thus pull out forward.
In fact- it already exclusively backs into spots when parking itself.
I think it's been adequately answered above. There will be times when there's no choice, either because of logistics or because of rules or laws requiring forward-in parking. Being unable to back out into cross-traffic is a serious shortcoming that is not answered by just saying "Don't do it."

Can you guess why this gentleman probably doesn't want his car backing into a parking spot?

Not really.
With a self driving car it backs in when it parks (IT ALREADY DOES THIS TODAY).
Then when he's done shopping he summons it curbside and loads up (IT ALREADY DOES THIS TODAY- though the range is short)
Then it drives him home. (TO BE ADDED AT A FUTURE DATE).
No reason backing in is a problem at all.
Try again.

Not every store has a loading zone.
I think you should just give it up. There will be situations where it's just not possible or convenient to back in, and an autonomous car has to be able to deal with that. The car's sensor suite has a blind spot, simple as that.

really? what stores selling large objecting needing to be loaded into the back of a car don't have any place you can pull up a car?
And yet you keep being unable to cite one.
Weird.
Are you really arguing that an autonomous car does not need 360° sensors? That a huge blind spot is no problem at all, as long as a small group of internet posters cannot think of situations where a car would need to back out other than building rules and local ordinances and people whose driveways open onto major highways?

It has 360 degree sensors.
Just not of the sort supporting rear cross traffic alert.
So far the only real example given was one that is only valid is it's NOT SELF DRIVING. Because if it is it'll come to you to load your long heavy stuff.
The other one was angled spots you can't back into- which isn't relevant at all since you're not backing out at a 90 degree blind angle from those.
Actually, two other important examples were given: Places where backing in is not allowed (saying, "Well, it should be allowed" is not an adequate answer); and private driveways opening directly onto a busy highway where stopping to back in could be dangerous.
Another major factor: time and manners. Imagine you’re pulling into the train station parking lot. The train comes in less than 5 minutes. There are people behind you pulling in that also want to catch the train. One of the rudest things you could do is hold up traffic behind you in your aisle backing into a slot. People get really frosted over that. I’ve seen back-ins nearly end in fisticuffs.
