OK, just to sanity check, because it's not clear from the comments below.
We all realize that metric areas do use hp for car engines as well, right?
And a lot of them also do inches for TVs, which is weird and forces you to go digging into the specs for the cm measurements whenever you want to see if a TV will fit in a space.
EDIT: Oh, I'm wondering now, do people use liters/cc for engine volumes in the US? I don't know, but I also haven't ever heard of a different way to refer to engine volume ever, so they must. What would they use instead?
EDIT 2: For my money the most annoying unit conversion in car measurements is the US going for miles per gallon, keeping the volume of fuel constant and giving you the distance while metric uses liters per 100km, keeping the distance and giving you the volume of fuel. It may as well be impossible to convert between the two.
Its just the old air cooled dinosaur old-man Harleys that show their engines in cubic inches. Here's a 975cc Harley. Here is a 750cc Harley. The sportsters have been listed in cc's for decades.
Suzuki does it too, on their cruisers. Like the M109.
we have to dig to the specs for tv size cuz the size of tvs is the diagonal screen area not the actual size
we use cubic centimeter for small displacement engines where the whole displacement is measured (is car) and cubic inches for the large ones where the displacement is measured per cylinder (ie trains)
I agree that most of the imperial system sucks, but knots (and by extention nautical miles) have a good reason for being used everywhere when navigating long distances around the globe because both are based on the way coordinates work.
The Fortwo never got anywhere near that much power, not even the Brabus versions. Toyota did make a one-off version of the similarly-sized Aygo called the Aygo Crazy which really did have 200hp and RWD though, so the idea did actually come into being at least once
The American truck complaining that the EU is too regulated, while in the US something as simple as headlights are so overregulated they blind people while driving.
In the EU the headlights simply aim their lights away from incoming traffic automatically, which was a crime in the US until like last year.

That only works like half the times at best. I'm still constantly getting my eyes lasered by big ass SUVs while driving at night. Not even counting the people that have misadjusted headlights.
Joules actually are Newton-metres, in a sense. A joule is (genuinely) defined as the work done when a 1 Newton force displaces a mass by one metre. So as long as you're willing to risk the Bureau international des poids et mesures assassinating you for your physics crimes, you can totally pretend that Newton-metres are for measuring energy and Nm/s is a reasonable way to measure power. While you're at it, you should measure torque in Coulomb-volts for the same reason
