My 2010 T2 does the same thing. Almost any modern car will if it has some decent aerodynamics. Because it's so cold here in the winter, I see it all day long on pretty much every car. Only pickups with the tail pipe sticking out the side do it differently.
Not sure why you think it is a poor design.
