This Covers it All

My Chavrutah lived in Israel for about a decade,

He once told me that one year, several days before Pesach, he witnessed a fellow putting aluminum foil over the steering wheel, dashboard, etc. in his car, just as "shtick".

By the next morning, such covering became ubiquitous throughout his Yishuv. And now you know, the rest of the story.
