If you have an air compressor, use it to blow out the hose during the winter and you'll never have to worry about it being frozen

At the faucet/outletI I keep a garden hose “splitter” on my hoses. In order to Clear out the hoses…all that’s necessary is to turn the faucet OFF….. then OPEN the splitter valves…and blow air thru one side of the splitter…which feeds air to the hose-side…and clears out the hose.

A portable compressed air tank is helpful for this task. (Every farmer/rancher/handy-man has a portable air tank…right…???)

Or you can be like me and have a hot and cold hose bib inside your garage. Yup my on demand water tank is in my garage, so I ran a hot water line right next to the cold water line. When I shut my garage doors neither line freezes, because I have heat and AC in there as well.

I’m not following your solution…. Because I have water lines which leave the garage…
Some of them serve the yard…the garden…the out-buildings. Almost all of them run either overhead thru the attic or below, beneath the pier-and-beam foundation of the home. They are insulated with foam-tubes…which are not fully-effective in 16-degree weather without addt’l measures. (hot-water re-circulation in the hot-water system helps…but doesn’t protect the other lines.)

So, my question is “How does closing the garage protect the remaining system outside that garage?”

Just go to a car wash with a undercarriage rinse and you should be good to go which is what I do when they put down salt and brine on the roads. I'm not sure a lawn sprinkler has sufficient pressure to wash away salt/brine on the bottom of your vehicle.

Pressure only matters if time does. As long as you don't mind leaving it longer and using more water, low pressure will do the same job.

Easy my hose bibs are on the inside of my garage. The out side lines are all run like yours. I open my garage door wash my trucks, when I finish I roll up the hose inside my heated garage and shut the door.

I was meaning I also ran a hot water line in my garage to wash my trucks, equipment with. This time of year I hate putting my hands into a cold bucket of water.

I'm guessing Frost Free outdoor taps aren't a big thing down south,but up here any outdoor tap usually has a "Frost Free Tap" installed on it.

I will say they are a thing here in TN. Last year I missed a hose hooked up on the side of my house (I normally take them all in during cold weather). When it got warmer, and I noticed it, I turned it on, and the freeze plug had gone bad. I had to rebuild it. This year before the cold hit I walked around the house twice.
