For road trips? Let's just say that from Northern Virginia to Williamsburg is about a 160-180 mile trip. About every 3-5 miles there are exits. Imagine that at every intersection, a voice cuts into your music, softly telling you to KEEP DRIVING STRAIGHT, then your music comes blasting back again

Yea, but then you would completely miss the turn off for Jefferson's Home and an easy opportunity to deface the campus of VA Tech. Not that I would ever do a thing like that.

I used to live in Norfolk so I know the exact roads you speak of. The drive to DC would be a beast as well.
