That's great! I love it!
It reminds me of my German Shepherd in my '82 Mustang GT. I would let the back seat down for him and he would jump in through the hatch. I tried to drive nice when he was back there, but once I forgot and snap-shifted second and goosed it, and he did a back-flip back there and wound up stuffed in to the back corner with BIG eyes. I felt so bad but I couldn't stop laughing!
