Luxury and Tight Quarters

Hubby and I went out to eat with our son and daughter-in-law for her birthday. Her father also went along. We met the son at a parking lot and all got in his vehicle, one of those crossover models. The parents sat in the back of the 5 passenger car. Son took off before we could get our seat belts on. So he had to stop and wait. We had a big laugh because it was such tight quarters that we couldn't put our belts on at the same time. And with the doors closed, there was no where to lean to give the others more room. On our return trip, hubby waited outside the car while her dad buckled, then me in the middle, and finally he got in and buckled. Wonder if that is in the owner's manual?
