First, they came for our light bulbs. Now they want to ban all cell phone use in cars:

The National Transportation Safety Board said on Tuesday that it had voted to recommend the ban on the use of mobile devices by drivers, citing what it said were the risks of distracted driving.

The recommended ban applies to hands-free devices, a recommendation that goes further than any state law to date. The agency said it is recommending that drivers be allowed to use their phones for emergency purposes.

“No call, no text, no update is worth a human life,” said Deborah A. P. Hersman, chairman of the N.T.S.B., an independent federal agency that is responsible for promoting traffic safety and investigating accidents and their causes. It will be up to the states to decide whether they want to follow the agency’s recommendation.

She said the decision was a hard one because such a ban would be unpopular among some people. But she said its time had come, given what she said were growing distractions in the car and the spread of increasingly powerful mobile devices.

However,  a researcher at Wayne State University in Detroit says not so fast.

In the new report, Richard A. Young of Wayne State University School of Medicine in Detroit finds that two influential studies on the subject might have overestimated the risk.

The problem has to do with the studies’ methods, according to Young. Both studies a 1997 study from Canada, and one done in Australia in 2005 were “case-crossover” studies.

The researchers recruited people who had been in a crash, and then used their billing records to compare their cellphone use around the time of the crash with their cell use during the same time period the week before (called a “control window”).

But the issue with that, Young writes in the journal Epidemiology, is that people may not have been driving during that entire control window.

Such “part-time” driving, he says, would necessarily cut the odds of having a crash (and possibly reduce people’s cell use) during the control window and make it seem like cellphone use is a bigger crash risk than it is.

The two studies in question asked people whether they had been driving during the control windows, but they did not account for part-time driving, Young says.

Just like the global warming hoax, researchers overstate data supporting their desired results. Then, government bureaucrats latch on to the flawed research, increasing their reach into every facet of our lives.
