I said "kind of", jelly face. Meaning it's easier.
You also said "necessary". Who knew that might confuse people?
It's "necessary" unless you want to sacrifice the hotter running temp and efficient burn and simplicity that you got from not building an engine inside an engine. If that's not what you're going for, then what's the point going to the rear?
Your word choice was poor. Nothing is ever "kind of necessary". It is or it isn't. And the point of building the engine to the rear is to take advantage of the lower air pressure behind the vehicle in motion that sucks the hot air out of the engine compartment. It certainly wasn't a requirement for rear engines to be air cooled.
Uhhh.... don't think so. If air pressure were the consideration why were air-cooled engines developed as long ago as the 1880s and in production since the 1920s? And what of the motorcycles and lawnmowers?
Air cooling is simply more efficient in terms of heat and power generation, as well as fuel efficiency and weight/complexity. It doesn't require a separate water jacket and pump and all that shit. If you're old enough to remember how common overheated radiators and failed water pumps were you have an idea why that's a consideration. It's a lighter engine all things being equal too, and when you're moving your centre of gravity back that far you'd better take that into account. Witness the atrocious oversteer problems the Corvair had.
On the downside it can spew dirtier exhaust, but that clearly wasn't a consideration in 1960.
Principles of aerodynamics.
A rear-mounted engine has empty air (often at a lower pressure) behind it when moving, allowing more efficient cooling for air-cooled vehicles.

Even back in the day they were smarter than you.
There were no "aerodynamics" considerations in the driving speeds of 1887 (when Benz experimented with it) or the 1920s (when GM and Tatra both tried it out and the latter put it into production). What you've made a case for here is the question of where an air cooled engine is more advantageously mounted. That was never the question.
Look, you and Finger-boy are continuing this for no other purpose than to argue. Redfish, who floated the absurdity that Corvair "copied" VW, has finally given up his absurdity in the face of logic. Which means, ironically, that Finger Boy won that argument, yet continues to argue with the guy who handed him victory.
Some people. SMH.
