Unarmed versus vehicles, Silly question until that STR 10. Options

[frostPDP]

What exactly ARE rules for damaging vehicles with unarmed combat? What about lifting them over?

A powerful blow with Killing hands is really just a very powerful blow, considering I don't see magic reacting to a car door that much. But how much strength IS strength 10?

The barrier ratings are hard to handle. Silly almost, when compared with damage to vehicles. Main reason: I don't see "vehicle metal" anywhere.

But that's aside from the point. Strength 3 is average human. Strength 4 might be a well physically fit guy, and strength 5 a very well fit guy, professional athlete and whatnot. Strength 6 is like Arnold used to be, and truth be told I could picture him putting a hand through a car door with a wound up punch. But maybe that's overestimation.

Still, being a good 4 points above THAT? If a decrepid old lady under adreneline rushes can lift a car (She had to be, what, strength 2?) then this guy could possibly lift and throw said car!

So what are the numbers? Are there any? Surely a STR 10 Adept can't put his hand through a Citymaster of a tank. But a Ford Americar? I say: Yes.

Lifting a citymaster, not necessarily putting a hand through it? I dunno.

So what is it? :)
