Call me old and cranky, but I’m ready to throttle Progressive Corp. and its persistent quest to raise auto insurance premiums for Maine drivers of a certain age. Why? Because, as I prepare to turn 62 this week, I’m a better driver than I’ve ever been, that’s why. And because when I turn 65 three years hence, the last thing I’ll be in the mood to do is feed the insurance industry’s need for greed. More on all of that in a minute.
