Dont really know is this the right spot

But can some1 provide me a script that makes an A.I. operated vehicle go from waypoint-to-waypoint with full throttle always on & a script to make it ignore any object on the way ?

Already done, check this for more details. At the moment it's only useful on relatively flat terrain, but will be edited soon

for now just change the 0 in this line:

?xcs_allowMove : _car setVelocity [_x,_y,0]

Make it a negative number, ie: 0.5, and play around with it until you get the right effects.
