How to make a bot AI car that will walk a road and the Player car can chase it?

Hello being new to unity I dont know much scripting
What I need for my game is that an enemy is trying run away from the player and the objective of the player is to catch him. So its like a car race :smile: and then a fight scene.So what should be done in order so that the bot car moves on its own and so how at a particular place if the player catches the car and a collision occurs and a sound. Then the enemy car stops.

How is it possible any explanations for me to do it? Whats the correct approach?
It seems like impossible to me as if the car and the enemy car are running at max speed then how the player can catch?
What is this will be the intellgent scripting please helpā€¦ :confused: Its my projectā€¦

you could make the player vehicle faster (supercopcar!!)
you could make the AI follow a path which isnā€™t very efficient (AI sticks to the road, but the player can mount the pavement)
you can add in other vehicles that the AI has to ā€œhandleā€ moving around causing it to brake/swurve/not move at top speed and expect the player to be better at working out a fast path through.

To start with the first option is probably the simplestā€¦ but these are design decisions which will change how you approach building the AI and the game.
