We do have 4x4s.
I didn't want an actual 4x4 at the time- I wanted something versatile that I could haul kids in. I've had it for eight years now, and it has served me well. My only complaint is that it's rear wheel drive, so it's not good in snow.

Mrs. L, it depends on the vehicle. If you're talking a convertible sedan, then yes, it does increase the drag- but that's only really an issue of you're going over 30 mph or so, in which case you're going to get windblown anyway, and probably you want that and don't really care about the drag. *grin*

Ever seen a pickup truck with a cover over the bed? It's not there to shelter the stuff in the bed- it's to keep the tailgate from acting like a parachute. Over here we have these plastic web gates you can put on the back that let the air through if you don't have a cover. It's actually illegal to drive with the tailgate down or missing, but you get a lot better mileage if you do.

Oh, and BGB? It's guys like us who think of these things who come up with things that save fuel and money and lead to better vehicles. You should be grateful that someone thinks these things through. *poke*
