This is a question Driven to Madness

Captain Placid asks: What annoying things do significant others, workmates and other people in general do that drive you up the wall? Do you want to kill your other half over their obsessive fridge magnet collection? Driven to distraction over your manager's continued use of Comic Sans (The Font of Champions)? Tell us.

But the engine is running anyway to turn the wheels. The energy to turn the cogs and stuff would just go to waste otherwise. I think you're over complicating how things really work.

The load on the alternator is proportional to the current draw. Not something that you notice on most cars, but on a small engine with a large alternator, the drop in revs when you start up a high current electrical service is very noticeable.

I had a small rental car in the 'states once
Parked with the engine running I noticed the revs drop when I moved the steering wheel a little bit.

I put on the air-con, heated windscreen, lights and heated seats, then waggled the steering wheel vigarously and nearly managed to stall the poor thing.

It all adds up!
