Well then just pop open the hood and look! Research the basics in how your car works before you kill yourself or someone else over your ignorance!
If you’re going to own a car, you have to follow the maintenance schedule religiously. You can’t just drive until something breaks. Even if you pay someone else to do the actual labor, knowing how your car works and when things need to be maintained/replaced can save you from a much larger repair bill in the future, because you did your due diligence and didn’t just turn up the radio when the car started making a strange noise. You did your research and know exactly what to say to the mechanic when you bring it in, saving you money not only because you addressed a small problem before it became a big one, but also because you’re not someone who can be easily lied to about the actual state of their vehicle so the shop can make more money.
If you can’t handle learning how your car works, then don’t own a car. Stop polluting the air so much and just take public transport instead.
The irony is that EVs are much simpler than an internal combustion engine by an order of magnitude. Electric motors are basically just magnets and wires. An ICE has pistons, connecting rods, valves, spark plugs, camshafts, intake and exhaust systems, etc.
