Steering others cars

Imagine a highway on which all of us are driving our cars. We can obviously drive our car the way we want. 

But aren't we often frustrated about not driving our car to it's full potential. We end up with wishful thinking and regrets.

Now imagine this - while driving our own car, we decided to call someone we care for. A few minutes into the call, we realize that he is not driving his car perfectly (as per us). And then we start sharing driving tips. he didn't ask for it but our good intention and deep love makes us share this unasked advice. And then we try to persuade him to drive his car in a way we feel appropriate. 

He doesn't take our advice and we are the more frustrated. 

Then why do we always try to steer others car? 

Why can't we focus on our driving?
