The vehicles are driving on the left side of the road, which is common in Southern Africa. The road markings and the general landscape, including the dry vegetation and specific style of road signs, strongly suggest South Africa. The presence of white pickup trucks (bakkies) is a very common sight there. The highway infrastructure and the overcast sky are consistent with the Gauteng region. I am fairly confident this is in South Africa, likely near Johannesburg.

then: forward

The green highway signs are distinctively South African, and the exit sign mentions "R55" and "Kyalami," which confirms the location is in the Gauteng province. The landscape and the specific architecture of the nearby industrial buildings are characteristic of the area between Johannesburg and Pretoria. Driving remains on the left, consistent with the previous observation. I am very sure this is near the Kyalami area in South Africa.
