There is exactly one car on sale in the US that meets the 58 MPG standard. The reason European cars are able to produce the wonderful gas mileage you are talking about is that they have less stringent safety standards. Stop pretending you understand the issues and admit that the only way to get high mileage cars is to kill more people.
Are you serious?
I don't think you know what you are talking about.
What part do you think I don't know what I am talking about? The safety standards? Europe does not require the same side impact testing, rear impact testing, and they only require the full on frontal impact testing, not the newer 25% frontal standards we have in the US. Additionally, they do not require cars to protect people who do not where seat belts, have lower roll over standards, and have different rules for the placement, and protection, of crash test dummies. The US just started testing using dummies that are specifically designed to simulate the average adult female in the driver seat. All of this adds weight to the car, and thus reduces gas mileage.
This site is uglier than fuck, but it shows the differences.
Everything Crash - Crash Testing Safety Standards for Europe & the USA
I am talking about your last statement.
You know the part about killing more people. Show me where more people are killed in automobile accidents in Germany in the United Kingdom where they have different safety standards.
I will give you a clue you can't. They actually have less deaths per capita.
And you might want to look into the safety records of BMW and VW.
