The Feds

Regulations are a 2 edged sword. They can help or hurt. Cars in the 60's cost about $3,000. Today they are??? A lot of improvements have been due to competition and racing also. Chrysler cars typically are more efficent and did not require as many add ons to meet emissions. You also get to a point of diminishing returns. Cars today put out almost "0" bad emissions. It took multi port fuel injection and computer monitored and controlled engine functions. Racers are all about efficency. We want the most power out of the same size engine put out by the factory. My 64 Barracuda was capable of high 20's mpg cruising on the highway with a HIPO 273 and a 4 speed. I got better milage at 70 than 55. So the blanket 55 MPH regulation was stupid for my car. Thanks to South Dakota, that stupidity is dead. No regulation can make sense for everyone. Regulation is a one size fits all.
