If it’s raining, there’s snow on the ground, or many other low traction scenarios, the cop would have to really want to pull you over. Chances are they won’t.
On a clear, dry day, depending on where you are, barking your tires is a violation of nuisance laws. Again, most likely not getting pulled over unless you consistently did it.
Now, if you stomped on it and your tires broke loose, you are looking at reckless operation of a motor vehicle. Expect to be stopped.
It mostly comes down to conditions and level of egregiousness… and how bad of a day the cop is having / wanting you to have.
That’s a good sized heater. It could be filled with sediment and not working efficiently. If you haven’t emptied it recently, it might be worth it.
If it’s clean, you can try turning it up. It will make full-hot from your faucet hotter, so be careful of scalding yourself, but it will make the hot water last longer.
You could also get a slightly lower flow shower head. Using less water at a time will allow it to last longer and keep do better keeping up with the empty rate.
If none of that works or is something you want to try, you could always replace with a tankless and never run out. Though you’ll waste a bit more water each time you turn on the hot since it takes a few seconds to kick in, but you won’t run out.
