Like sad movies, cars are good for moving people, but you don't always want them around. Make automobiles abide by your schedule with today's Groupon from OccasionalCar. Choose between the following options:

• For $20, you get a new year-long "Simple" or "Trendy" membership, including the application fee (a $25 value), $40 worth of driving credits, and the annual fee (a $50 value and a $115 total value).
• For $10, you get $20 worth of driving credits for existing members.

With 19 Denverland pickup locations, OccasionalCar allows members to rent its fleet of Toyota Yaris or Honda Civic Hybrid automobiles by the hour or day. Rates and mileage depend on the day and time, but gas, insurance, and permanent parking are all provided for each member, ensuring that quick jaunts to the supermarket, tattoo parlor, or the Bermuda Triangle can be undertaken without worry. The Trendy plan features no monthly fee and offers sporadic motorists 10 free miles per hour of rental, or those wanting lower rates can opt for the Simple membership. In addition to eliminating the ever-mounting costs of car ownership, OccasionalCar's buggy-sharing system cuts down on traffic congestion and helps Mother Nature continue her omnipotent reign over Earth by reducing greenhouse-gas emissions.
