There were many advantages to the infant carrier. First off, it was easy to get in and out of the car. I guess I should say easier. Second, if the kid is asleep you can just bring the whole thing up and set it on the floor. No waking. And finally, you could take the seat out and go right to a stroller.
I worked for a company that sold baby stuff for several years. I will not say which "R" I might get in trouble (wink, wink). I learned many a skill while working there. One of which was how to install a car seat. For those of you who have not done this since car seats evolved past a bucket and a bungee cord, let me give you a picture of what that entails.
Okay, so now that the seat is installed, you can try it out with your little one. I am not a small guy. I'm not quite as round as I am tall, but clearly Hondas are made for small people. Like any two door car with a back seat, they figure making the door six inches wider will be adequate space for people to climb on in. It is hard enough for me to get in the back seat by myself. Adding a 20lb child to my chest who think it is fun to wiggle about while we squeeze through the doorway does not help. I have to basically get in backward clutching Hugh to my chest and make loud coughing noises to disguise the sound of a baby's head bouncing off of weather seal and interior paneling. Additionally, I cover this up by acting surprised when he seems to always fall asleep once he is strapped in. Additionally, the seat belt is mounted to the floor in such a way that it is always stretched across your path in perfect position to ensnare and take you down. This usually happens more when you are getting out. You step back and for some reason your foot never reaches the ground.
When he is asleep, you might as well forget it. I have resorted to the mother cat pick him up by the back of the neck with my mouth style.
