Key context: thermodynamics dictates that heat engines waste a lot of energy.

I think the 80% number is outdated (although most of the energy is still wasted)

F1 engines achieve a peak thermal efficiency above 50 percent, significantly higher than a modern passenger car's 35 percent thermal efficiency - https://www.motor1.com/news/655596/video-how-f1-engines-make-1000hp/

So more like 65% goes out the tailpipe...

I'll have you know 65% does not go out of my tail pipe.

It goes out a hole in the exhaust manifold that I'm too poor to patch up.

If your rolling coal, you are literally pumping unused diesel fuel out the car. You're efficiency is absolute dog shit.
