Re: Driving Under The Radar
Images v. sight & hearing: -5 to Perception, Set effect: totally inconspicuous vehicle, Persistent. Anyone looking at the vehicle will still perceive it... but it'll look completely ordinary.
This should probably be expanded to effect several hexes, so it covers the whole vehicle. Also, depending on how "foolproof" you want it, the penalty could be higher. If the road trip in question is really long (several days, coast-to-coast, whatever) then I'd go with a -10 to Perception. Otherwise, someone's gonna roll a perfect three and spot the car at some point.
