This is just about 500 m from the site of the accident. I doubt the authority would set the speed limit to 60 kph on this kind of road. Not just bends, there are many junctions with no road marking at all, and shops or housing area entrances just by the roadside. Common sense tells me, even a 50 kph speed limit is already high.
There was someone who said 80 kph.......

Since the car was probably going down a slope from the overhead bridge, and the road in front is a little wider, I assume he/she increased the speed. So, at the site of the accident (probably the + junction), the car was most likely quite fast, very likely exceeding the limit (speed limit won't increase just because there is a slope). As a result, it took about 45-50 meters to stop. This is the distance between the + junction and the entrance of housing area where the CCTV is.
Since speed limits are there to reduce harm, the driver caused serious harm because of failure to drive at or below the limit, he/she cannot claim 0 fault.
