My thoughts are leaning towards Central America (ish). We already know that the cars are driving on the right so that should rule out Hong Kong and we have a 1950's/60's scene that looks tropical with a VW and something large and American driving past. The fact that the road is so close to the runway threshold suggests to me that a coastline (sea/lake/river) lies next to the road.
Given the above, and purely as a guess, I go for the airfield on the eastern side of the inlet at Guantanamo Bay.
