My family had one when I was a kid too, and we all loved it. My initial thought here is: is there a way to bring these back safer? Some sort of mechanism or even computer control that requires the seats to be locked in a safe orientation before the van can move, and prevents them from swiveling unless it is parked? Backwards-facing seats might even be safer than front-facing ones for all I know.

But I'm also remind of how big it was. The US already has a problem with too many huge private vehicles on the road. As much as I liked this as a kid, I think today we would see too many single adults driving these things to and from work most of the time. We need to take more cars off the road to make room for these: public transportation, walk ability, cycling infrastructure, smaller cars, etc.
