Do you like to take a vehicle from Haarlem to Amsterdam and return it at the Amsterdam hub? Or from The Hague to Rotterdam?
Unfortunately, that is not possible.
You should always end your ride at the hub from which you took the vehicle.
Therefore it is not possible to leave your vehicle at another Hely hub or elsewhere.
Of course you can park your vehicle elsewhere on the way, but then you do not end your ride in the app.
