Wrong!!! They get data on the PERFORMANCE of the vehicle from road their own road tests, slaloms, skid pads, bumper bashers, etc. All that silly crap they think is important.
They might get opinion surveys, but they conduct their own irrelevant tests to come to some of the dumbest conclusions on equipment they have NO CLUE how to operate in a real world enviroment. The original intent of a diesel pickup is not used to go through a slalom, or go to a race track. It was made for WORK.
Show me a CR test where the full size truck gets equipped with a rack & boxes loaded with tools & lumber or a snowplow. You can't and no matter how much you say you love CR (Communist Reports) they just don't cut it when it comes to testing commercial trucks, or many other pieces of equipment for that matter.
So Double-DUH to you!
