I'm not complaining about members of the public using a public road. I'm complaining about a company
directing its users to take routes which were never designed as throughways; routes which few if any of those users would have taken
but for Waze directing them.
Imagine you own a large parcel of land with a public easement for crossing to a beach. Every day a few dozen people walk across. Now imagine I put together a party and direct 3,000 friends to walk across your parcel all at once. As large crowds of people do, they stray and destroy things. Your mailbox. A small bridge crossing a creek that you own and maintain (thankfully nobody is hurt).
But for my party and the people I invited, none of this damage would have happened.
Not only did I create a credible nuisance (actionably by itself), it's not too much of a stretch to say I could be held vicariously liable for the damages. All this even though it was a public right-of-way.
In the absence of relief (self-policing, civil liability), I can tell you what is likely happen with the Waze issue. States will pass laws that require Waze and others to exclude routes upon notice by state authorities. A database will emerge of impermissible throughways. Neighborhoods and towns will scramble to add their streets to the database. Violations will come with huge fines whether or not actual harm occurs, even if the violation was exceptional (i.e. reroutes through blacklisted streets during a traffic accident). Ultimately the only routes you'll be given are truck routes.
This has already begun, it's just voluntary, and Waze doesn't cooperate. That's not going to last long. Waze will ruin the space for everybody else by inviting heavy-handed regulation.
