It isn’t like these doors tensions are standardized. How much pressure to apply to the trunk door of this car you’ve never ridden in before? No idea, it might even be the auto closing kind. Thankfully, most Ubers are priuses, but not always.
That's why you should push doors/trunks/hatches closed and not throw/shove/fling them. I don't mean "push", as in close it like your closing the front door after sneaking home after curfew in high school. I mean it more like keep your hand on the door and slowly accelerate until you've given it enough momentum.
You aren’t pushing so much as pulling. It is much more difficult to control from the inside. Anyways, I just don’t ride in enough cars to get used to the different tensions (maybe if I took Uber more). Also, it always seems to be the American sedans that have the most problems, which we don’t have too many of on the west coast.
I can understand that. Honestly, my experience with modern midsize sedans (Altima in particular, Accord, Camry, Sonata, etc) is that the manufacturers view the rear doors as throwaway areas for "engineering" weight out of the car. The rear doors on these cars honestly weigh about half what the fronts weigh and they fly open and close as if made of paper maché.
