I would definitely use one of these :)
I'd rather see people using one of these than the dog running around, on the driver's lap, being petted or fed, etc. They still look ridiculous, though.
Okay, obviously I'm comment-happy today. But, I just found your blog and I heart it. I actually have that carseat for my malti-poo, Fred. He loves it. The ac can hit his face and he can ride with the windown down (without my paranoid fear that he might bounce out of it). I know it is psycho. I can't help myself.
