No
Never tried to hit a vehicle. Just joshin'. Although if I did, I've heard that a swing Dutchman, with a tree moving somewhat horizontal, is your best cut.
The best running a road block story I have is from South Carolina. Wasn't there, but I'll tell it like I was.
Prescribed burn, major road (45) closed off with FS vehicles and barriers.
First road block, coming from the north, laid out poorly just before a curve. Two guys in a rig big enough to carry the back hoe on the bed barrel through like they're important. Everyone scatters and has visions of hell, being transferred to the Daniel Boone NF and finishing their career as a timber marker. The guys in the truck, when they get to the second road block, end up diving for the ditch and half roll their rig.
The FS folks come running up ready for a full meal EMT event followed by years of paperwork. The two law abiding members of the public, who both have outstanding warrants, split on their two good legs through the woods faster than anybody can catch them. (However, they left a few tons of identification behind)
Everyone is still catching their breath on that one. In the NASCAR South, a road block is not a device to stop or slow traffic; it is a personal challenge that was no doubt brought in by some Yankee carpetbagger.
