Since when did one relinquish their rights at the airport? -it wasn't always that way.
According to Originalists like Scalia and Thomas (who have been reliably most protective of 4th Amendment rights) , it has always been that way in the sense that persons have always had less of an expectation of privacy at ports.
To the extent that these devices were being used to observe individuals without a search warrant, any evidence discovered would not be admissible in court. The general rule (though IANAC[riminal]L) is that unless the technology is generally available to the public, then a search warrant is necessary to use it for evidence gathering purposes.
That doesn't negate the general invasion of privacy this technology poses, and each technology must be evaluated on its impact.
I call it corporatism.
How rarefied is the electric-car demographic? When Deloitte Consulting interviewed industry experts and 2,000 potential buyers, it found that from now until 2020, only "young, very high income individuals" — from households making more than $200,000 a year — would even be interested in plug-in hybrids or all-electric cars.
Lane also takes issue with the billions of dollars in subsidies offered to automakers for the manufacture of batteries, arguing that research (warning, PDF) concludes that the money will not help in jump-starting the economies of scale that will drive down prices. At least, not as much or as quickly as the President has argued.
The Obama administration claims that offering subsidies for early adopters will open a wider market for electric vehicles, bringing costs down to mass-market levels. Lane counters that such a market does not exist because the majority of Americans have no interest in purchasing electric cars.
Of all the findings in Deloitte's market research, the most poignant was its profile of electric car "non-adopters." They have average household incomes of $54,000, live in the suburbs and rural areas, and depend heavily on their cars. There are millions and millions of non-adopters all across America. They are the middle class.
