This may sound silly, but when driving I always use the sun visor to block the sun. Quite often in the afternoon it comes shooting into my driver-side window so I extend the visor as much as I can for full sun blockage. That's when my problem happns; I arrive at my destination, put up my windows and then see that my window has hit my visor and comes back down. When I hit my window up, it would be ideal if my visor could pull back in to avoid this from happening. I know this sounds lazy, but it happens all the time. An automatic retraction of the visor would prevent this. In some cars setabelts retract (luxury convertibles offer this so that the back seat passengers have an easier time of getting in). Retractable visor can't be far behind.
