Scooter services have their share of issues, but Lime will at least make sure there's a scooter to use in the first place. In the wake of a limited release in three countries, Lime has made scooter reservations available in the US ahead of an international rollout later in the week. If you know you'll need a two-wheeler in the next 15 minutes, you can book one through the app instead of hoping that it'll still be around when you're ready to ride. You can still grab another scooter if it's more convenient, of course -- it'll just release the scooter you'd reserved.
