It's ironic that you mention diminishing returns, as many automobiles in the $200,000+ range appreciate in value, rather than depreciate. A $60,000 car is still, by all objective standards, a luxury car. Mercedes-Benz, founded by the inventor of the automobile, Karl Benz, has consistently been the leader in automotive innovation, particularly in safety features. http://www.mbusa.com/mercedes/benz/innovation http://www.mbusa.com/mercedes/benz/innovation Top speed is not the only desirable attribute of a powerful car. Accelerating to 75mph in 4 seconds is an enjoyable experience in its own right. Additionally, does the speed limit actually stop people from driving as fast as they want? Where I live, the speed limit most accurately describes the lower limit, not the upper. "Everyone" may, perhaps, be construed as an overwhelming majority, but not a simple majority. A majority of voters selected Barack Obama as President of The United States in 2012. It would not be accurate to state that everyone selected Barack Obama as President.
