SeekSteer problem...

Hi Unity users…
I recently took the SeekSteer script from http://www.unifycommunity.com/wiki/index.php?title=SeekSteer

And I have a problem.
I attached the script to a cube and set the first waypoint.When my cube reaches the first waypoint it keeps moving,it doesn’t stop at the waypoint and crashed into a wall then comes back…
My script is exactly as in the link above…

And here is a picture:

Thanks in advance.

Have you tried to tweek the damping(up) that will make it stop on a dime and not let the velocity carry it past too much?

So what you making? Some AI cars.
