I don't think that car insurence will really have a blast in BTC. You are paying it once a year or once a month and you can convert your BTCs for that.
I completely agree but I am all about being the "first" to accept BTC. I was so happy to finally introduce a MMO gold site and was the first to accept BTC as a payment form. In order for me to offer BTC for car insurance I need to gauge interest in it.
Let me explain the type of insurance this will be the license is not for any specific one company. How this works is I run some info on your current coverage with a lot of various companies to find the absolute lowest rate possible.
Why I want to offer this is for something promotional worthy but to make it even worth while I need to really see if offering this to the bitcoin realm if it would actually be supported, and lets face it we need something positive in the bitcoin scene.
