Many issues to contend with here and I think Matt laid out a simple and good summary of them.

My (very long) thoughts on this. I do hope you'll read them.

As someone who knows next to nothing about anything outside of federal regulatory stuff....(Yes, I'm a hell of a cocktail date *ZZZzzzzzzz8)

Driving on the highway [does not equal emblem here] driving the EPA highway cycle. If they were out on Route 53 from Romeo I'll wager they were driving 70-80MPH - which is way faster than the EPA cycle and would net a lower MPG.

Awesome. Feel free to contact me as I'm a bit of a policy / data nerd and have spent the last few years blogging about, well, things NHTSA / policy / etc. juan.barnett at gmail
