Better yet, why this came out soon after the EPA decided to dump toxic mine waste into a river in Colorado? This smells of a diversion to make the EPA look good for a few weeks.
One item that is puzzling to me is the actual test protocol has not been discussed or referenced in any articles I have seen. Ultimately what is requires and how it is done is the key to whether this is mostly smoke & mirrors or a real scandal. I am inclined to believe when the dust settles this affair is combination of VW being a little too sharp and the EPA (mostly) having a mostly worthless test protocol.
