Smart on the highway

Hello, I’ve always had ridicule and ridicule for Smart, until recently a colleague took me with him (for now), since then I’ve gone and think about buying such a vehicle myself. However, I wonder how it is on the highway. Is one taken seriously and enough power to overtake? Or is one forced to drive to the eternal right. And how is it on long distances with the comfort or with strong wind? Questions about question but maybe someone can answer it?!
