In hot weather, there is a car's reflection on the expressway in the distance. What happened?

The pavement is paved with asphalt (commonly known as asphalt), which will soften in case of high temperature. Sometimes shoes get stuck when walking on them, and it is dark and bright in the distance, just like sprinkling water. This kind of situation only exists on asphalt roads. If you don't believe me, look at the cement road. There is definitely no cement road.

The main reason is that the sun is too strong.
