Those American Pickups Can Be Fast...
Those factory tuned pickups can be damn fast. 2007 Ford Lightning runs 5.3 0-60 and is blown...guy in my neighborhood has a Sonoma (or some such Chevy truck) and runs at least headers, exhaust, chip and a 80 or 100 shot...they can go really fast in a straight line and I imagine their draw in "picking on" a BMW is to see the look of shock on the owner's (yuppie's?) face as they fly by...which, to an extent, I can understand. No reason to drive dangerously, but I can see it.
Don't underestimate their acceleration capabilities or how easily modded they can be.
And don't underestimate a 70/30 weight split and all power to the rear wheels, Mr Pickup Driver... LOL
