> getting denied the vehicle they reserved Why do car rental companies have such a problem with this? I haven't rented a car in 5 years, but I rented a bunch in the 5 years before that. I don't think even once I was actually able to get the car I reserved, they are always out. There's even a joke from the '90s in Seinfeld about this. Why are car rentals so much worse than other industries with reservations? Rarely would this happen at a restaurant or a hotel. Only cars seem to have this problem.
