ThEoNeAnDoNlY,
Not necessary to delete the waypoint. You can override it with a trigger.
Creat a trigger (activated however you want).
You can use whatever names you want, just for this example:
Name your truck (QRF)
Name your charactor (BOB)
In the On Activation field, put: QRF domove getpos BOB;
Whenever that trigger is activated, the truck will move directly to your position.
Goodluck,
