Educational Car Driving for WEB

Hi.. i want to create an educational driving game .. but i dont have idea how to start it .. i want to apply the real rules the game . but all i can do is to make the car move Please help me .

May I ask if the car bumped to a wall or car what will happen? if your car keeps moving like a ghost that passes or overlaps the objects. I think you should set the on collision with other objects

if the car bumped or hit the other car it will back to the starting line or there will be pop up message that will says "Be care in Driving etc." my idea is like this () ..

I am thinking if you can use physics plugin on these or just the on collision action of sprite.

what type of physics plugin sir ? thanks Mr. DayDream
