Imposing laws to protect people from themselves are nothing new. The issue is what happens to those laws once it is found that they don't work. For example- researchers have found that laws that ban cellphone use while driving DO NOT prevent car accidents.
From the New York Times: "Laws banning cellphone use while driving apparently haven’t reduced crashes, according to a study released on Friday that compared the number of total crashes before the ban with the number after. The study found virtually no difference in the numbers, a finding that had the researchers scratching their heads."
Now the question is, will the laws be repealed? Probably not. After all, there is still a lot of money to be made selling headphones and devices to "make us safe." In fact, I am willing to bet that communities will continue to propose "no talking while driving laws" despite the evidence the laws are a failure.
