Because your car has a battery. The battery can provide power to the lights, accessories, but most importantly the starter, which is used to crank and start the engine. If you leave those accessories on while the engine is off, it will drain the battery (we're talking leaving these things on for hours without running the engine). Drain the battery enough and it won't have enough power to start the engine.

Your car also has an alternator, which is basically just a small generator turned by the engine. The alternator turns some of the engine's power into electricity to power various parts of the engine as well as the lights and accessories, while also recharging the battery.

The ICE does power all the electronics.

All car engines have a generator ("alternator") attached, which generates the electricity that the car needs. Taking power from that generator puts a drag on the engine's shaft, requiring more fuel to be burnt to keep the car going at the same speed. There is no such thing as free energy, it has to come from somewhere.

There is also a rechargeable battery in the car, used when the engine is off. That battery is recharged from the generator when the engine is running. So any power taken from that battery, requires more power from the ICE to recharge the battery. Again, no free energy.

Air conditioning usually connects the AC compressor directly to the engine shaft (via belts). Again, when it is running that puts a drag on the engine's shaft, requiring more fuel to be burnt to keep the car going at the same speed. (The AC needs a lot of power, so this design avoids the inefficiencies of having the generator drive a big electric motor to drive the compressor. It also avoids the weight and space for a big electric motor).

No offense, but you should just google “what powers the radio in my car?” r/Rev_Creflo_Baller is right, it’s the alternator (when the cars on) and battery (when the cars off). Guess what powers the battery and alternator?

However, this claim implies that your digestive system is unable to adapt its secretions to the consistency of a meal, which is false

Only for a relatively short time until your battery is dead. The 12V system while the engine is running is supplied by the alternator, the battery just buffers it.

As proof, you can jump a car without a battery and the electronics will all work.

Because you have a small charged battery which is used to start the car.

Run the radio for a while without starting the car, and your battery dies, and needs to be jump started.

It's this related to quaternions?

I’m the early 80s, Datsun hatchbacks were rated at 42mpg Highway. In the late 20’s you could achieve 25mpg in a Ford. Neither was very safe or luxurious though.
While I’m amazed by the low emissions of modern engines, we should have better mpg by now. Too many amenities, weight, etc on newer cars for my taste.

When the car is off the power comes from the battery. The batt gets charged by the alternator when the engine is running.

Another commenter mentioned that you can substitute calculations in electronic circuits that would normally use imaginary numbers instead with vectors. But it's a lot more work doing that, whereas imaginary numbers make calculations easier to do.

It seems like imaginary numbers provide a way of rotating between magnitudes in a sine/cosine way

There you go. First person to have the correct answer!

Some of these ruins stood for over a few hundred years. They were often large artistic buildings for different cultural things. So people just left it there because it has just always been there. Space and land weren't as tight and it would be more work to clear it away to rebuild then to just build somewhere else.

Fuel injection helped alotcwith that

Yep. The engine powers the alternator which generates electricity needed for the rest of the car.

Tried it, was not a fan, though I know others like it. Good price, tastes better than 1800, OK in a marg. May even compete well in the price range, but I'd rather spend more on something I really enjoy.

Of course it does. That's what the alternator is for. That plus keeping the battery charged up.

Someone’s still salty about 1776 I see. /s

The maximum efficiency of an ideal combustion engine (Carnot cycle) is only 50%. This is a theoretical limit, no real engine can actually reach this efficiency. The fact that we have engines in the 30% range is already pretty impressive.

Why aren't the improvements bigger? Well, because the closer you get to that limit the harder it is to get closer to it. In other words, it takes increasingly bigger technological and engineering advances to make increasingly smaller improvements to efficiency as you approach that limit.

Well same reason why we have abandoned industrial complexes, old abandoned buildings and such. People need to be willing to do something with that ground. Removing ruins takes time and money too... the amount of just burned down or abandoned buildings that litter our modern landscape is quite vast too.

In many cases ruins also just just stay landmarks

This is today. Back then all they had were hand tools...not explosives, heavy machinery, cranes and all that.

You are not just "removing" structures that are as solid as lets say the roman colluseum

Often times ruins also tend to be mostly foundations.. no one bothered to remove foundations

So they very much did remove a bunch of it. Just.. put dirt over it and use the square as a market or something.

Other times.. well cities get abandoned by conquest too... whoever conquered the place doesnt necissarily see maintainance of some places as needed.

If europe wasn't rebuilt with massive efforts after ww2 most of these ruins would still be here.. this is how many war torn countries will remain to look like for loong times.

I understand your point that the name is not logical. I understand the states of matter. My point is that languages aren't always consistent. No one gets confused about the fact that gasoline is actually a liquid.

Have you tried Tanqueray Rangpur? It makes any gin drink that you’re going to make with lime taste even better.
