I had two thoughts about this:
1. I've been pretty cynical about the petitions to government (although I did sign that one), so it's nice to see some notice being taken of an issue like this. A reasonable case was made, people signed the petition and the powers that be have acted. Good stuff!
2. I agree that many (most?) drivers aren't terribly up to date with the HC. I do sometimes wonder whether it would be better to make people resit their driving test every x many years (or more frequently if they start racking up points on their driving license). I'm sure this would do wonders for keeping people in touch with what the HC
actually says rather than what they would
like it to say!
It would also foster a different attitude towards the 'right' to drive - i.e. that it isn't for life and passing the test isn't a one-time thing.
However, I don't ever expect to see the UK government pushing that idea - it would be suicide by ballot box.
