The reason you don't park beside fire hydrants is in case there's an emergency, the firefighters need direct and quick access to the hydrant. If they have to maneuver the hose around your car, it takes away valuable water pressure. If you're parked close, it makes it hard to unscrew the hydrant and attach the hose. I've seen them smash out a person's car windows because they couldn't get access to the hydrant otherwise. Not to mention, if they have to fiddle and work around your car, they're wasting valuable time that could be spent dealing with an emergency. It takes literally seconds for a fire to go from manageable to inferno. Don't park beside hydrants.

I witnessed the same thing, them breaking the windows out of a car and running the hose through the car. Even better if that the car flooded! It was a nice Mercedes or BMW, I can't remember which.

Then you should be able to buy a permit that says you don't mind having your car smashed... It saves time for everyone

I'm pretty sure just having common sense and Not parking in front of a fire hydrant will save time for everyone.

I don't think you understand. Parking beside hydrants makes a potential emergency harder and more dangerous than it already is. It isn't about you and what you don't mind being done to your car, it's about other people and the potential harm you could cause them for what is merely a minor inconvenience to you. Don't be selfish, you can find parking somewhere else, a hydrant, however, can't be moved and is usually the only one accessible within the vicinity. You shouldn't be allowed to park near them, period.

If a hydrant can be the only one available why can't the space near it be the only space available?

How can common sense make a physically nonexistent parking space appear?
