(Not an argument against Waymo doing better in this situation though!)
Not so much police cars, anymore.
Back in the time of the B-Body Caprice and the Crown Vic, sure. These days with the exception of the Tahoe the most common police vehicles are all unibody platforms. Charger, Durango, Explorer, Taurus, and the rare Australian Caprice
You can still bolt a push bumper to them and most departments do, but they have to be used with a lot more caution and a lot less aggression to avoid damaging the vehicle than in the days of body-on-frame sedans.
Fire trucks on the other hand, yeah they're basically the opposite in that there might be a couple of Explorers or Durangos in the fleet but most everything else is a medium duty truck or a custom chassis specifically for fire service.
Pretty sure that's always the expectation? It's typical to tow illegally parked cars, smash windows to run hoses through cars blocking hydrants, etc.
The only unusual thing here would be holding a corporation to account the way we hold individuals to account.
Chances are the damage will be solely on your vehicle, as fire trucks and police vehicles are equipped to push stuff off the road without damage to their equipment.
don't be a dick, don't block the road
