You also have to account for the fact that the earth itself attracts asteroids even if they're not heading 100% towards the earth, though I'm not sure how large of an effect that is at interplanetary speeds

Am I the only one who actually enjoys the headrush?

So I started researching and Wikipedia actually has a calculation on this and for an asteroid with hyperbolic excess velocity of 12.5 km/s the effective increase of the cross sectional impact area is 80%. Not x10 or anything but not insignificant either.
The impact is going to be larger than that for objects that approach the earth from nearby orbits.
