<human>: Give me a shortened version of the text

I'm currently a full time student at a university living the majority of the year there. I rarely ever drove the car back home, if at all, while at home before going to school let alone now. The car belongs to my grandfather whom I live with. His insurance company recently contacted him about adding me to his insurance for an additional $1400(usd) a year. They told him if he does not take action then they will nullify his policy. The questions are the following: Is it possible to forfeit my license and avoid this whole thing? Is there an alternative method that could possibly enable me to keep my license? 

Extra facts: They do have record that I live in the house. I have lived there for several years. There is one record of me driving the car on permission from my grandfather.
<bot>: Insurance company wants extra money from my grandfather for me on his policy, and I don't drive the car or live at home most the year.
