The vehicles are driving on the left side of the road, which points towards countries like New Zealand, Australia, or Japan. The vegetation, specifically the flax-like plants on the left, strongly suggests a New Zealand landscape. The red painted curb and the specific style of the guardrail are very common on New Zealand mountain roads. The cloudy, misty weather is also typical for high-altitude roads in the North Island of New Zealand. I suspect this is near the Rimutaka Range or a similar mountainous pass in New Zealand.

I am fairly sure this is in New Zealand.
