Is speed control a matter of safety or philosophy?

Philosophy or Safety?
I read an interesting blog – by one of those Libertarians who advocates the kind of “freedom” that rides roughshod over the freedoms of everyone else. In this case, it is the freedom to speed in a car or motorbike.
The cause of this puerile outburst which you can read here: http://tinyurl.com/q2b5le – is the new GPS speed governor which is being developed in Australia. “Freedom dies with GPS speed governor” wails Alexander Mark. His argument is that this is another step along the road to a “dictatorship of rules” against which we will all one day rebel.
Now, in a sense, I’m in agreement with Mr Mark about this dictatorship of rules – we are slowly being hemmed in by regulations and contractual requirements. The former have been instigated by governments who have put in place laws that govern our behaviour and require us to behave as good consumers and the latter are the contractual obligations allowed by these laws that require us to pay forever for things we have already bought.
