That should be approximately 50%, considering that the Earth is round, and the Sun is almost a point-source at a fairly large distance (compared to the size of the Earth). This does not consider clouds or mountains blocking sunlight. Considering that we don't see the Sun exactly as a point, as well as atmospheric refraction, the actual percentage is somewhat larger - once again, if you don't consider mountains or clouds.

Why on earth not? Cars are cars - if they are street-legal, the sun has nothing to do with when you can drive them.
