The Volkswagen ‘Side Assist’ is a new feature “that will help drivers see the usual blind spot that drivers have.” The improvement is a wider mirror that will help make “shoulder checks” unnecessary. The improvement is simple, as are Volkswagen’s efforts to get the word out about it.

Volkswagen sent a man out onto the street to tap people on the shoulder and step away. When they look over their shoulder, the unsuspecting people turn around to find no one there. After being poked, the man explains why he poked them, and gives them a card to tell them more about Volkswagen’s Side Assist.’

This trick is nothing new, but it is a clever way to emphasize how annoying it is when you can’t see what’s behind you on the streets.
