Car looks spotless https://www.hemmings.com/classifieds/dealer/oldsmobile/custom-cruiser/2035765.html
It does look exceptional: Sadly, it's a 90: "What could possibly go wrong?" People can get ejected if the door opens in a collision, that's what.
I suppose a lot of people who know these cars and bought them new were not enthused about it. I heard of a few cases where that happened but this seat belt system wasn't just on 1990 B Bodies, it was on a few other G.M. cars for some years after that.
Notice though..... been how many years now????, since you have seen a production car roll off the line with the eject=omg=matic door mount seat belts.................
Very nice car and nice to see how GM tried out new ways to meet safety standards back in the day. Imagine what happened as late as the early sixties when we didn't even have seat belts. Most likely the amount of miles this car is going to see in the future makes the seat belts not as much of a risk. However good article from the 90's on this very design: To quote: "In one accident, the petition said, a youngster in a children's seat that was being held by the automatic belt ''swung out like he was on a trapeze'' when the door opened at low speed. The child suffered minor injuries." http://www.nytimes.com/1990/09/15/style/consumer-s-world-gm-is-challenged-over-seat-belts.html
It never even occurred to me to leave the seat belt buckled in and open and close the door when I had my '90. Egads what a horrid design. Almost as annoying as the Nissan\Honda "automatic" seat belts that used to come up and choke you when you turned the car on. Shame people couldn't be bothered to just put the stupid belt on so that the feds had to intervene...
I have no issue with those that wish to not buckle their seat belt, calling it an invasion of privacy or whatever.... My personal opinion is, if they fail to have their seat belt fastened properly, then they forgo all insurance coverage for their injuries. Why should society shoulder the cost of their stupidity?
