New car mileage

I'm all for getting regulation OUT of the automotive industry. The government has never known how to build a vehicle.
And I remember the Vega's and Pinto's of the 70's. Competition within the industry got us better cars, But 50 years down the road the last reincarnation of the Dodge Dart was not much to write home about. Evidence that corporate vehicle planners can still get it wrong.

And this is a bit off topic, but what amazes me today is the number of 8 to 10 year old Ram and Chevy full size truck that have significant rust around the rear wheel wells. It seems that the manufacturers have been able to fix the rust problems on cars, but not trucks. I would be PO'D if my 10 year old truck got rusty.
And this is likley something seen in the Northern states and not so much on the South.
