Does Waymo's app give you the ability to cancel a trip before the trip start, with no penalty?

[xnx]

Yes. I haven't had to do this myself, but I just read someones account of doing just that (because of delay, not mess).

Cancellation fees may apply, especially if you do it late, or you're a no-show.

If you purchase a GoPass, you'll receive a 10% discount on all rides, and 5 free cancellations.
