sure do. some because the engine is transverse (the crank is parallel to the front wheels and a mechanical fan would be blowing out the side) some because of packaging where a large cooling fan would not fit. there are still clutch fans in service, usually in the most extreme duty cases.
also, let it be said that all oem electric fan setups, every one of them, have millions of dollars of R&D by hundreds of engineers involved with all aspects of the fan turning on and turn off, software coding, cooling efficiency, reliability, servicing, testing in extreme climates and a lot of other things that the home builder guy picking a fan from summit and a thermo switch from amazon is not concerned with.
but I agree he doesnt have room for a clutch fan.
