I'd guess it's really that you talk to him in the car so he has to be that much more awake to add that to his multitasking, to drive at the same amount of safety.

SGU would definitely be my answer. You couldn't ask for a better show to do it with either, because of the way it ended it would be easy to have had problems with stasis to explain why some of the actors didn't come back or even the aging of all the ones who do come back. So easy to write around the long time it was off air and still pick up and run with it.

Do you know where you can find the mini series to watch? I've been wanting to start into bsg finally but haven't found those to start with.
