My experience with Progressive is that they started out being competitive and every year raised their rates until they were no longer.
They did cover my accident on the BMW K1100 I had prior to getting my Yamaha RSTD. However, their adjuster cut a deal with the MC shop doing the repairs, and when all the money was spent (and 6 months had elapsed), only 1/2 the BMW had been repaired, it still leaked oil severely and there were scratches over much of the MC that didn't get re-painted or parts replaced.
I wound up walking away from the motorcycle for $1000 which the shop gave me for it as-is. That basically covered my deductible out of pocket expenses. Net, I got nothing. My bad, I should have taken the initial insurance company settlement. But I wanted the bike repaired.
I probably should have sued the shop and Progressive, but I wasn't willing to invest the time and energy into going to court.
