Yeah, the car is just tagging an aspect, I agree.
The reason I don't like the grappling option is because 1) it's a multi-round affair, and 2) the range is really limited.
When Harry
blasts the Loup-Garou through the wall of the police station in Fool moon and knocks Magog into the next zip code in Small Favors
it happened instantly, at least in terms of exchanges, he obviously wasn't "setting up" a magical grapple on one round, maintaining it through his opponent's action, and then activating the push the next round.
In both examples above, the subject moved through at least one zone if not more. The first moved through a wall, onto a street, through another wall, and into the building across the street. Assuming the walls are only a one point barrier and the street is a single zone across, that's 4 zones. the second example is a little less clear, but it seems to take his target at least a few exchanges to make it back, so I'd say it's clearly more than 1 zone.
Moving things is more about mass than might. Sure, a black court vampire might have inhuman or even supernatural might, but they're dessicated corpses, in all likelyhood they'll fly
farther than a human despite the fact that they could rip that human limb from limb with little effort.
I will probably use Control (Spirit or Air) vs. Athletics to dodge. The number of zones travelled will depend on the shifts spent on power: 1 zone for 1 shift, 2 zones for 3 shifts, 3 zones for 6 shifts, and 4 zones at 10(!) shifts(someone better at math than me can put the progression into mathematical terms). Damage would be incedental, if the victim passes through a zone barrier it suffers stress equal to the value of the barrier, and I would never have someone suffer falling damage, even if I need to "cheat" to make sure they land somewhere soft.
