Speak for yourself! As I've always told people when they bring up the point that they don't like the idea of anchor points and wards moving together...

How do you reconcile this with the rotation of the earth, or the warding of rooms with, say, doors that swivel outward or inward, or skyscrapers, which flex and move in relation to their base anchor point whenever there's wind?

I understand the resistance to warded vehicles, but it's necessary for two major reasons:

1) Large craft such as aircraft carriers or cruise ships would be unable to secure area via wards, even though reasonably one can ward a room inside a ship, because the "vehicle" is moving.
2) It's necessary to prevent utter dominance of spirits in any kind of military combat - spirits may manifest within any craft be it a suborbital or a tank, and down it with a trivial expenditure of powers, unless there is a mage defending each an every military vehicle.

I would suggest setting a lower limit on the Body of any vehicle to be warded, however, as well as the restriction on being enclosed.

You do know that the Accident Power works without the Spirit entering a Vehicle, Right? And the theoretical Ward inside does bupkiss. (IMG:style_emoticons/default/nyahnyah.gif)

Personally the notion that a ward is good to move so long as it's moving uniformly is garbage, it can either move or it can't.

Where is the anchor then?

A ward is anchored to an object inside the ward. If this object moves, without the entire warded area moving in tandem with it, the ward breaks down.
It's simple enough, really.

Except as far as I recall, the accident power has to act upon a victim, not an inanimate object - the power increases the chance of a glitch & critical glitch. Since the object cannot roll dice, it cannot botch, only the pilot. The pilot - or pilot software - is inside the ward, and therefore is protected by the ward.

Even if that's not the case, the accident power is shit for downing planes. Increase the chances of a botch when a pilot has a halfway decent amount of dice and a copilot? Pfeh. Manifest in cockpit, engulf pilots, laugh all the way down!

Consider the difference between: I am warding this vehicle, binding the ward to a widget bolted to the vehicle, and I am warding this vehicle, binding the ward to a rock that I throw in the trunk.

No it's not. What makes the ward sometimes move with its anchor, sometimes not?

Do I get a Cookie?
Damn: Mardrax got there first... (IMG:style_emoticons/default/frown.gif)

I'm starting to picture Bill O' Reily's face here. (IMG:style_emoticons/default/wobble.gif)

Don't worry there TJ, if I get a cookie, you can have half. You'll get the half with most chocolate chips even!

got you beat there:

Ah, crud!
Would you like a share of the cookie too?

Read it again. Forces a Crash Test with a Penalty equal to the Force of the Spirit. Any Non-Piloted Drone immediately crashes if the Spirit is Force 3 or so, since the pilot will no longer be able to generate the necessary Hits Threshold (3) at that point. At Force 6, even a Piloted Vehicle may have issues. Of course, Living Pilots have Edge.

I dunno, even at Force 6, burning people alive is more reliable. A competent pilot - 4 dice in his skill (or 2 with a specialty), 4 Response in his commlink, hot sim + Control Rig, and a handling of 0? He's got 10 dice before accident, AND a -1 threshold from being in hot sim. Conversely, he probably has no way to handle a Force 6 spirit murdering him in the driver's seat or cockpit.

I can't "read it again", since I don't have my book at work.

Non-piloted drones statistically will crash 1/3rd of the time they're forced to make "very easy" vehicle tests on a semi-crowded street ANYWAY. Logic REALLY suggests any drone should have a rating 3 autosoft installed along with its 3 Pilot rating, because otherwise they cannot take off or land reliably on their own.
