Where does your baby sit in the car?

This is going to lead into a big rant but I wanted to find out first where other people have their infants carseat installed in their car.

Okay, Brenna sits behind the passenger seat for tons of reasons... the two cars seats (hers and Zachs) do not fit properly in the car if the bulky infant seat is in the middle, I can see her which is important to me since she has reflux, I can reach her to pop her paci back in her mouth, and I don't have to adjust the passenger seat each time I put her in which I would have to with the driver seat.
So anyway, Haley sits in the middle and Zach's seat is behind the driver seat. I went to drop them off at school this morning, reached back and opened up the back seat door, and let the kids out on the opposite side that the sidewalk is on. A teacher comes up to the car and says "You need to let them out on the other side". I said "I can't because of the baby". She says "Can't you move the carseats?". NO I CAN'T! and I told her that. I actually said "No, because I can't see the baby when she is behind me". The teacher looked at me, said "It's a safety concern", and walked off. It's not really a huge safety concern... they are getting out of the car in a controlled single file line of one way traffic with tons of other parents and teachers around. It takes them 30 seconds to get to the sidewalk. I could fix that 30 sec. inconveniece and "safety concern" and then go through an entire of day of inconvenience and safety concerns with my infant.
It just really irritated the crap out of me.
Tomorrow I should go pull up, turn the car off (because it's a safety concern to leaving it running with children alone in it), walk around the car to the passenger side, take Brenna and her carseat out of the car, and then let my kids get out on the passenger side. Then of course I have to put Brenna back in and walk back around to the other side, the entire time backing up traffic, and restart my car before pulling out.

They are both in the back... just at opposite doors instead of the infant seat being in the middle like I would prefer.

Just to clarify things...
There is a row of 5 teachers standing at the edge of the parking lot, they let 5 cars pull up at a time and one teacher assists each car in getting their children out, shutting doors, etc. to prevent the parents from having to get out and delay the line of traffic. We have a cop at each end of the line directing traffic and keeping people moving in the right direction.
The only thing my children are doing is getting out on the drivers side of the car instead of the passenger side where the school would prefer them to. They aren't walking through a busy street unattended, sitting in the front seat of the car, or anything else irresponsible on my part.
I CAN'T SEE OR REACH MY INFANT WHO HAS BAD REFLUX IF SHE IS SITTING BEHIND ME... that is the only point that I want the school to understand and to be open to excepting that not all families can comply to their preffered method.
