The only ones that usually go for car rides are Jack and Micki, they absolutely love car rides and expect to go everytime I grab my keys BUT they only go if I'm just running a few errands or something, I would NEVER ever leave them alone in the car more than 10 minutes if I can help it!

OR if we're travelling and staying in hotels and such, then I would much much rather have them staying in the car then alone at the hotel, but thats a completely different situation...
