Yeah - that pretty much sums it up, athough it's a bit of a stereotype.
Friends g/f had a coolent leak in her car, and the temp gauge was slowly rising over a period of time - she didn't even think to check the coolent level and kept driving it. Anyway one day she went on a longer trip than usual, and it rose right up to the red, but she didn't even pull over, just kept going until the poor car did a head and she had to pull over... but yeah, unfortunatly most people have probably heard a story or two like that.
