This happened to me days ago and I wasn't charged for the cancellation, as far as I can tell. Not sure if it's because I called and cancelled sooner, there's no reason to wait to call if you see them driving the wrong way. Either that, or they detect a driver not making progress towards the pickup location when they decide whether to charge for the cancellation.
