The last time I went to a Chinese restaurant, a station wagon was parked outside, packed to the gills with about 80% magazines and books and 20% household items... (Detailed question continued below.)?

Sounds like someone with issues, keeping all of that non car stuff piled in the car, or someone living it it.  But quite frankly, why are you so concerned?  If you think it is a criminal issue, or someone in need of assistance call the local cop shop and report it!

Sounds like a hoarding issue for sure! Usually they leave just the drivers seat open so they can get in.....scary.

The last time I went to a Chinese restaurant, a station wagon was parked outside, packed to the gills with about 80% magazines and books and 20% household items. It looked like someone had been living in it for quite some time, but they had a book and magazine addiction. When I left, I noticed it was gone. Someone had driven it away. What could possibly cause someone to drive a car around loaded up like that?

It was similar to this:

What causes that is the same thing that causes a person to stockpile all kinds of stuff in their house. I used to live next door to a hoarder. There was so much crap stacked in his garage that when one side collapsed the roof stayed up. I had to cal the city to come out to get him to fix it. (I hat to think of the rodents in there.)
