My point is this. At some point, civil disobedience becomes a duty. When the law is so out of step with public opinion it is oppressive, then the time has come to ignore that law.
It is true for the consumption of harmless halluciongenic drugs such as cannabis or DMT, and it is true for speeding.
I did not elect a government to oppress the motorist who often has little choice of mode of transport. Why, when I am supporting the capitalist system, and providing employment for thousands, and tax revenues for the government by driving my car, also have to suffer the indignity of being told by the 'nanny state' how fast I can drive it, on the roads which I have paid for with my tax ?
Simple solution. Abolish all speed limits on motorways, and divert the police to catching real criminals instead of middle-class taxpayers such as myself.
Of course, there is no money to be made by this approach, far better to criminalize a whole section of society in order to make a profit.
