Several years ago I got the chance to balloon in such a thingie myself - it was a great adventure. On my way home from a client some weeks ago this balloon hovered just above the street where I was driving. I thought it would land and stopped by the street, but it pulled up again after scaring the hell out of some poor rabbits that fled from the field below.
... and yes, the windscreen of my car was dirty.
