Is the original post about car share or bike share?
I support both. We go to LGA to rent cars about once every three months. Its affordable and easy enough, but we often end up paying for an extra day when we only need a few extra hours. I remember in the car share proposal that cars would be parked in the neighborhood and parking spots would be allocated exclusively for those cars.
As for bike share..here are some trips I'd make regularly. I own and ride a bike but there are days when a one way bike trip is better. Such as going to drink/have dinner. Biking there, train home is better.
Trips up and down Queens Blvd, to shopping and appointments
Downtown Flushing
Any library
School meetings
LIC YMCA.
Groceries in Astoria
Bookshop in Astoria
Bagel shops in Astoria
Good bars in Astoria (we need some Astoria businesses here)
Glendale, Maspeth, Ridgewood
Sunnyside, woodside- lots of old school, small town businesses that are worth the trip.
Greenpoint
Trader Joes on Metropolitan
And most important----- As a connection and backup to the E,F,G,M,R trains that often have delays.
If one were able to use a metrocard to hop on a Citibike, we'd see expansion and an increase in ridership like never before. (or like the transit strike of 2005).
