It would be interesting to test your claimed common law right to travel with the the UK courts? especially since UK law is all common law based?
Where I live a MDL is often cancelled as a punishment for not paying a fine, eg you did not vote!!!! - most times you do not even know your license is cancelled. When Police stop you, using smart number plate recognition, they charge you for driving without a license - a more serious offence. Then you have to re-sit your drivers license with all the newbies, maybe waiting list of 10 weeks or so + expensive fees. This is how absurd being "free" is in a so called western democarcy!
UK courts operate a hgg hmm 'hybrid' system whereby they will attempt to NOT use common law at every opportunity and will switch to the revenue generation method of statutes and acts whenever possible. Only those who realise this and use the correct language will get the courts to honor common law and those do not typically include lawyers.
Switching the courts to the older jurisdiction is done though and you can see videos of it on youtube (filmed 'illegally' according to the courts). As I recall, the language is 'traveling in a conveyance' rather than 'driving a motor vehicle/car'. ;)
