Oh.. Damn.

I've never thought of that!?

Always, when I'm driving long distances, my eyes keep turning off and just close (or it feels like it) so I try to force them open, because I've always wanted to just watch what goes on out there and daydream.

But I could just let it, and dream instead! Perhaps lucid!

Cool. Thanks.
Other than that, I've never actually fallen asleep in a car. I'm very certain that I can, I've just never done it.

It does also sound like the perfect lucid enviroment, constant movement and sitting position should up your awareness...
