This is the problem - folks like you who have a legitimate use for these large vehicles, and (in my experience) a good working knowledge of the performance and limitations do end up getting a bad name because of the huge proliferation of the "soccer mom" type, who can't drive, have no spacial awareness, no reflexes to speak of and are just generally crap.

A good truck driver, when given a space, will be able to spot it, move into it and indicate his thanks, while a typical SUV driver (again, the "soccer mom" type) won't even see the space until it's too late, then try and get into it, causing everyone to hit the anchors, then realise things are a bit tight and brake heavily or swerve and then give you the finger when you try to pass her as she's sitting at speed limit minus 10 for the next 40 miles.

Akkkk - can you tell I hate them
