I was in Alexandria last week for my Mother-in-laws 90th birthday. We stayed with my brother-in-law, Paul, and sister-in-law, Cheryl. They have a small garage and as we were going out Cheryl bragged about her remote folding mirrors (On a 2008 Mercedes-Benz C-Class Sport)
Warren is right, many car dealers have them now. Audi, BMW, Honda, Chevy. They fold as soon as you click the lock or unlock. very cool.
