They just appeared seemingly overnight here recently. They seem quite popular, but aren't really practical on rainy days. Will see what happens when winter really hits. I can't imagine many people preferring them to a car on a snowy, slushy day or with temps below freezing. Also wondering how they'll handle salt exposure, and how the cold will affect battery life.
