Startup Idea : Monthly membership based car rental service

I purpose a service that offers people to have the same luxury and reliability of owning their own vehicle but at a better value and without having to worry about depreciating vehicles and high interest payments. I want to offer people the convienence of having a reliable source of transportation anytime of day anywhere but once their destinations met they no longer need to worry they swipe their time card put the keys in the designated lock box and their mobile app records how much time the vehicle was in use and move along to work or diner or whatever they have planned for themselves. I'd like to offer different packages based upon the needs of each households, business or organization. Ranging from economy packages to student packages to luxury. From individual rates to family plans to business based group rates. I haven't worked on pricing and a la cart promotional additions. id like to include safety features for younger and beginner drivers and to provide peace of mind to parents of students gone away to college or university. Whatever the needs of today's driver are Id like community car rentals to provide.
