You could store the dot positions....

Wall(1,1) = x2
Wall(1,2) = y2
dot x2,y2

you are drawing dots on the screen, and each dot has an X/Y coordinate. You need..

Dim(How many dots,2)

Rem......This is like .. Dim(400,X,Y)

As your motorbike draws a dot store it in the array.

You then use a distance formula to see if you hit the dot.

You could also put a sprite on top of the nearest dots for collision.

Actually...you could create screen zones wherever a bike travels. A screen zone is a rectangle area, with an X1/Y1 X2/Y2 top left/ bottom right rectangle. These zones are like invisible collision areas usually used for buttons. But it would be quite easy to use them for invisible walls. Or you could just make collision boxes. The best way to learn zones, is to make a button that you can click on. You will probably need buttons in your game anyway.

I'm making something similar to this. I'm making Breakout, and it has squares all over the place as bricks. I have found that you only need the X/Y coordinats for the collision. You don't need X1/Y1 X2/Y2. Once you have the X/Y coordinates you already know the radius of each dot.
