I read an alternative history novel once where all the cars looked and operated just like our cars on the road, but they were all STEAM engines rather than ICE engines. Not the focus of the story, but the only issue was throttlability (no surprise to woodstove owners). Wealthy car owners just had chauffeurs that kept their car boilers stoked on standby, or in advance of the boss needing a drive. Poor folks took the steam powered bus, or stoked their own cars. All in all it sounded a lot more practical than horses, and almost as functional as ICE cars.
Of course, to our eyes the whole rigamarole of stoking and solid fuel handling seemed kinda crazy, but to the folks in that universe it was completely normal...and it suited their needs and economy seamlessly. Their car owners raved about acceleration, loved the whirring and purring of the steam engine, the smell of the smoke, the tone of the steam whistles they used for horns. We are an adaptable species.
That story may have permanently changed how I look at ICE engines now. I see them as a functional technology with a certain amount of utility, that obviously powered a lot of 20th century applications. But at the same time, ABSURD. Internal combustion? Necessarily incomplete mixing and combustion, high temperature NOx production or both, yuk. Pistons with oil-sealed rings? A mechanically inefficient kludge, with run lifetimes merely in the thousands of hours before complete rebuild is required? Yuk.
Nissan nailed it with this ad:

All your debates about DIY repair: you are making the argument. Only crappy tech needs constant repair, especially after a century of engineering!
