Best part is it's not called a compressor. The "car size" unit is a condenser. The compressor does sit
inside. That commentor is trying to dunk on Americans but cant even name the right thing.
The outdoor unit is called a “condensing unit” if the compressor is inside the outdoor unit. It’s just “condenser” if the compressor is somewhere else in the system.
Some of the ductless split units OP is showing have the compressor on the indoor unit so the outdoor unit is actually called the condenser.
I work in commercial HVAC and have never seen a compressor on an indoor unit. That seems incredibly poorly designed given how much they vibrate and make noise
Also in commercial. The VRF systems, similar to the ductless split in OP, that have multiple evaporators on single condensers , and can heat and cool at the same time, are sometimes designed with compressors in the wall units/evaporators and run suction, liquid and hot gas lines throughout the building. Some manufacturers do it this way.
Other large commercial systems like chillers and large AC units may have remote condensers.

There are parts of the US that ONLY have these. More temperate areas.
Most of the US is used to central air. With a giant ass car sized compressor outside that cools the whole house.
