Bruce T said "Insurance companies are cold, profit-making machines. They make massive profits. It's simple. They charge high premiums and award low claims. They sometimes refuse to pay until threatened with a non-frivolous lawsuit."
Depends upon the insurance company, and especially your agent. Although I haven't had one in over a decade I have over 250k miles on motorcycles, and always to have my points maxed out. The safest place to drive was in the #1 lane slowly passing traffic, but I also have made runs like San Diego to San Jose in 6 hrs, via Fresno :^) Anyway, I got dropped by my ex's insurance company, noticed a Farmers close to where I lived, walked in and said that I collected tickets like baseball cards, didn't get into accidents, and would he consider taking me on. He checked up on my record, said that on paper I was a bad risk, but still offered me a surprisingly affordable package for a Suzuki 1100 and a Yamaha 750. I accepted, thanked him, and have been with Farmers for almost 20 years now.
Insurance companies rely upon statistics to essentially make bets in their favor while still trying to be competitive with other companies doing the same thing. They work with huge databases and reliable statistical techniques. Some companies prefer to work with low risk pools exclusively, others will take on anyone for a price. Young males in most vehicles, especially sports cars and 4wd trucks, get into a lot of accidents and are a 'poor bet'. A good driving record offsets the risk a bit, but not as much as you'd think.
