How to determine when it's safe to pass

[ale03000]

Apparently a lot of drivers in my country don't know how to pass safely due to a number of reasons. Could be even due to lack of attitude/skill apart from ignorance.

only the ones who doesn't know how to measure or estimate traffic distances and speeds are dumb and less defensive drivers.

Q:How can you recognize that you are far ahead enough of the car you are passing?

A: When you see the whole car in your internal rear view mirror.
