I totally agree it's not being alarmist. I do have a very close friend who DOES, and I just don't discuss car safety with her anymore. She DID have her kids in very good seats (I recently bought her used Regent for my ds2.) but she doesn't have a problem with her kids getting unbuckled to reach something, or having them ride in the front, seat, etc. I personally am not really comfortable w/ that stuff, but it's her choice, you know?
As for travelling with a baby, highways always have emergency pullovers. Believe me, I use them all the time, and a cop has stopped to check more than once and every time told me it was perfectly OK to use the emergency pullovers to nurse my baby. It's MUCH safer than a regular shoulder, and it's definitely better than getting flustered trying to reach the next exit with a baby screaming. If a truck needs to use it, there's plenty of room. THere's usually enough room for 2-3 tractor trailers in a standard emergency pullover. And sometimes they even have picnic tables and trash cans.
It's also very easy to pump and give the baby a bottle if your baby takes one. I've done this before as well, and washed my pump parts in rest stop bathroom (with my own soap and towels.)
And I'll admit it, I have done the lean over with the boob trick, but I have enormous stretched out boobies. I don't have to actually lean over the car seat. I just have to turn a little sideways and bend over a bit and my 10 inch long boobs can reach.

I'm not really comfortable with it, but after being in the car for 12 hours or more, you get a little tired of pulling over every 20 min.
