if you h ad a truck, 2 people with you, and the penalty for failure was pure HORROR, would YOU just stop at a dozen motorcycles in the road? Man, If I was driving, you can bet there'd be pieces of bikes and riders go FLYING. but of course, in reality, anybody so dumb wouldn't last a week. you block rds with stuff you dont CARE about, and you take cover to the SIDES of the roadbloack, in a shtf thing, you'll probably have people possibly coming from BOTH directions. if you are the one doing the driving, you probably might as well eat your gun. big obvious, noisy vehicle, stuck moving along a given path, a highly known about path, with a vehicle that's probably full of goodies.
