The red painted curb line is a distinctive feature often found in New Zealand, and the vegetation looks like native flax or scrub typical of that region. The vehicles, including the white vans, are consistent with New Zealand's fleet. The road layout and the guardrail design strongly suggest a mountainous or coastal road in New Zealand. I am fairly confident this is in New Zealand, likely near a scenic lookout or a high-elevation pass.

I suspect this is in New Zealand, possibly near the Remarkables or a similar mountainous area. I am 70% sure.
