Had a claim a few years ago with Allstate. Time wasted on that took me out of 6 weeks of the best riding season on my CVO Ultra. Rather than just blame Allstate, in my case it was an adjuster who knew next to nothing about motorcycles, appeared to be somewhat prejudiced against motorcycles and riders in general, and perhaps was prejudiced against me in particular for whatever reason. After the agent intervening (said he could not but know that they can because eventually he did & others have in the past) and me meeting with the adjuster at the shop, all was resolved quickly. Do I love Allstate/hate Allstate? Neither. At this point in time, they are the best coverage for the cost I have found in my area. That changes at times, and my policy loyalty does not go with lowest cost always but it does move with the best cost/coverage offered.
Long time back was not that way on autos, M/Cs, & home. Stayed the same, major companies only, did not shop. Quite a few years ago after some hefty cost increases for no owner/operator reasons, I shopped. Man was I surprised at how much some companies were compared to others. If it's $10-20-50 bucks might not change just because of the hassle. Usually the difference is $200 or more when I do.
Insurance rates cannot be compared across areas as to exacts on premiums - in this case even inside the same state. Why? Lots of reasons, mainly has to do with cost of operation of a vehicle as to risk in given areas. Rates are set by actuaries who study stats then figure averages based on age, miles, driving records, etc. My comparing an insurance rate to your rate, unless you live in or near my zip code is like comparing the cost of an apple in an orchard to the price at a roadside stand 1,000 miles away. Same apple, different costs associated with it.
