What I still don't understand is what is going to happen in March 2011, if
they continue with the present logic, which is to use '0' to indicate March
registrations and '5' to indicate September and the other digit to represent
the last digit of the year! There will still be plenty of vehicles on the
road registered in March 2001 as aa01 abc. Should be interesting!


They won't. March 2001 will be XX11, and September XX61. That way, the
present system will last until September 2049, by which time we'll
probably not have any oil left to run cars on anyway!
