Why landscape mode?

[sketch]

For a while, I had a broken windshield mount, from which the phone cradle could be separated. The cradle, with my phone in it, fit perfectly sideways within the lid of the storage compartment below the radio in the Prius I had at the time. I couldn't justify spending $$ on a new mount at the time, so I used it like that for a while. It was pretty far from my line-of-sight, but it looked like it belonged there.
