Installing the carseat RFing can definitely be a little trickier, but I agree that you've got to get the car seat pros to show you how it's done and then practice, practice, practice until you're comfortable doing it properly yourself. It is really not too bad once you've done it a few times, and if you're comfortable doing it in your own car, you'll be able to figure out how to do it in another car fairly easily.
The first time I traveled with my son was when he was two months old. I'd had the police install the carseat and had never done it myself, so when I got to the destination, I was clueless. Luckily I was with my sister who has three kids, so she's had a little experience in that department.
