I saw one of these ladies the other day that somehow manages to endanger everyone around her despite driving a vehicle as tiny as a fly. She entered the Autobahn A3 in front of us. The truck already driving on the A3 along our cars was so kind to change to the middle one of the three lanes to make way for us. Once on the A3, we dropped back a little to make way for the truck to change back to the right lane, where he usually is. The lady however thought different. She just accelerated up to the exact same speed as the truck and stayed there.
But the truck started to hold up the following traffic big time, so he put on his indicators to imply that he'd like to change to the right lane. The lady however didn't do anything at all, she just sat in her lane, completely ignoring the outside life. The truck driver then blew his horn to adivse her of his presence. Not that it would be possible for anyone in any way, shape or form to overlook a 40-ton-truck when sitting in a car that's about as big as one of its tires, but anyway...
The lady finally understood what's going on, so she braked quite hard to make way for the truck. The truck immediately changed to the right lane, and the traffic started flowing along again. Now, the lady noticed that there is a hugeass truck in front of her, which, as we all know, many drivers simply can't accept, even if they only want to go 1 km/h faster than their newly discovered obstacle. So the lady indicated to the left and started changing lanes. Of course, the Audi A6 being right beside her wasn't too happy about that. It wasn't like he was to be missed as well, since the car was twice as big as the shoe the lady was driving, fully illuminated and simply flowing along with the surrounding traffic nicely.
She however for some reason decided that she has the right to pull over, so she continued to change lanes. The Audi actually had to pull a bit to the left to avoid a collision, blowing his horn. This animated the lady to give up her attempt to go bananas on the Audi and to pull back to her lane, let him pass and then change to the middle. Since she didn't accelerate at all after she had arrived there, we were easily able to pull along to see what's going on. Well ... all her windows (including the windscreen) were fully fogged up.
"Well officer, how should I have seen the truck and the limousine? I couldn't look out of my windows!"
