How to turn in the direction of movement?

Hi All, I hope to make the car move towards a goal every two seconds. How to make him have a fast animation of turning in the forward direction every time he starts moving. I don’t know how to calculate turning.
( In addition, is there any way to make each driving animation look smoother? Not change the target point update frequency)

Did you try looking there: Building a Track for a Carriage to Follow | Babylon.js Documentation

Thanks. Yes, it can make animation look smoother. But it may not apply to my function. my target point of each update is from websocket. So I dont know how to plan such a curve.
