I wonder how the subscription would respond to a person's area being blocked off.

There construction happening a block down the road from me. As part of the work, the rightmost lane is often blocked during the day (in between rush hours), so that things like concrete pumping can take place. The lane block starts just before where I live.

Around the same time, I noticed that when I would try to take Waymo (which I used to get to PT), I'd be told that things are busy and rides are paused. Recently, I've noticed that if I'm at work (or the PT place) and I want to take a Waymo back home, I'm told "Can't get to that spot right now".

If I had Waymo Premier, I wonder how hard it would be to get a refund on my subscription.

The above talks about a complete block (or, a complete-enough block) to using the service, but what about a major impediment? For example, let's say I travel regularly, and use Waymo to get to/from San Jose airport. Waymo's been disabling highway routes, which for me equates to 20-minute (or more) travel-time increase from home to airport. Would that be enough to qualify for a refund on the subscription?
