There used to be a Fisher Price infant seat which had just a strap like that attached to the seat and no handle. A lady I knew who had one really liked it.
I wish I had something like that for when I pick my daughter up from school (though I don't want it badly enough to spend the money to actually get one...). She's young enough that I go to the door to get her. This year I'm going to be lugging the infant seat along with me since I think baby will stay warmer left in the carseat with blankets undisturbed rather than being taken out and put back in again three minutes later in -30 weather. It's not that long of a walk, but it's awkward to carry the seat around by the handle, especially while holding my son's hand at the same time.

I use the handle. I find it easier than just carrying the seat even with two hands, and it's the only way to carry it with one hand if you need the other for holding onto another child or carrying something else.
Still awkward though. I generally avoid doing it by a combination of travel system and babywearing (often at the same time - a travel system can be useful for carrying a little shopping basket around the store while wearing a baby), but sometimes (like with the school pickups) it just works the best.
