From: "Dave Ings" 

I dunno. I don't think it's the passport per se that creates the (mental)
barrier. It's the border checkpoint with guards and (especially) long
queues that provides the primary incentive to drive the 20 miles versus the
5.

I really don't see the difference between flashing a drivers licence and
flashing a passport, all other things being equal.
