Interlingua is an International Auxiliary Language, but it is naturalistic (most features are extracted from widely spread Western Indo-European languages) unlike Esperanto which is systematic (highly schematicised).
Streetcar is incredibly easy to use. You sign up, and receive a smart card. When you need a car, you check and reserve online, even minutes before you need it, then go and pick it up (there are a few locations a few minutes’ walk from us). You unlock the car with your smart card, use it, get some fuel in paying with a card that bills Streetcar directly, then park it back where you found it and lock it with you card. We used it on Wednesday night and found it so hassle-free that we will definitely use it again soon. Worth it for short day trips, where it beats a traditional car-rental daily tariff, without the pain of having to pick up and return the car across town.
