I love Times Car Sharing and use it heavily, but I find the pricing structure a little bit obtuse: There are various "packs" for example a 6 hour pack, 12 hour pack etc. The 6 hour pack means you don't get charged anything extra for fuel/kilometer. The other packs do charge you a fixed rate per kilometer. There are also special packs at nighttime. The app doesn't really help you pick the best one for you or minimise your price. Here's an example: Book a car from 5.45 to 11.30. You're 15 minutes short of the 6 hour pack so you pay the basic time rate. Now change the booking to 5.45 to 11.45. You now pay the 6 hour rate (4000 yen iirc). Move the booking to 6 to midnight. Now you pay 2000 yen because it's night-time. Overall I love the car sharing experience, it sure as hell beats paying 20,000 yen a month for a car parking space. I just wish they made this a bit clearer/easier to use.
