How is driving?

I was driving this afternoon from office to home. I was in good mood because the traffic was light. Suddenly, the traffic became moderate then heavy. Then, I spotted the sign on the back door of the van I was following:

It made me smile and forgot about the heavy traffic. In a matter of minutes, the traffic flow became faster again. I might call the telephone number and complain to the owner of the van that its sign made me smile.
