Ruling that vehicles are not affected by toxins would be a house rule. Ruling that ghouls cannot cast spells at targets on the physical plane would also be a house rule.
As I've shown, ghouls can, although they take a -6 penalty for actions purely relying on physical sight. But, as Dr. Funk showed us, you can target either/or when dual-natured/astrally perceiving, so it's not casting purely on physical sight either.
Common sense is assumed. Whether people want to accept that
fact or not really isn't any of my concern.
If people keep up with that level of Stupid, then vehicles not only
are vulnerable to toxins, but they're vulnerable to all sorts of other effects that are full of even more Stupid. It all stems from the fact that vehicles have skin. This is a rule as written. It's found in
Arsenal on page 145. "For riggers, controlling a vehicle often gives them the illusion of
using the vehicle’s skin as their own." Rutroh! SR4A p. 254 details how Contact-vector toxins work thusly:
"Contact toxins (in liquid or gas form) must be applied to the target’s skin."Thus they're vulnerable to Contact vectors. Look ma, I can be a pedantic idiot, too! Say goodbye to AV ammo, say hello to Ringu Capsule Rounds!
Incidently, as previously pointed out, if that "common sense" thing doesn't step in this also means vehicles are prone to disorientation, nausea, and any and all other side effects contact-vector toxins, drugs and compounds have since there's absolutely no rules that say vehicles don't suffer from them. They even use the ambiguous term "target" when referring to the mechanics thereof. Case in point, SR4A p. 254:
"Disorientation: The target suffers a –2 dice pool modifier to all actions due to confusion and disorientation for 10 minutes." Additionally, since there's no rules that directly say vehicles don't have a heart, nerves, muscles, or other biological systems, they do as based upon any contact-vector toxin that mentions them affecting those systems.
I'm sorry, but anyone who adheres and follows the rules blindly is a fucking moron. Especially when they're doing so just to be an obnoxious dumbass.
