Here is the thing.......are these people God? Do they believe their way is the only right way?
No, they are not God, and yes, they believe their way is the only right way. Do you want to argue with the person who is testing you, who decides whether or not you get to have a driving license, or would you rather just drive the way they want you to drive for the 30 minutes of the test so you can pass?
I picked the second option, passed the test, and moved on with my life secure in the knowledge that a) I wouldn't have to pay another £62 to take the test again after failing on principle, and b) I wouldn't ever have to use the handbrake at a red light again.
While I fully understand the "The system should be changed!" argument, having now observed the bureaucratic ways of the UK when it comes to motoring, and more importantly, interacted with the type of older English gentlemen who make it their mission in life to espouse with pedantic glee the intricate details of motoring laws and regulations, fighting against the system would be a pointless and frustrating exercise.
