I totally agree @CellarDoor, its been interesting to see lots of differing views aired.
I had some thoughts about licencing (funnily enough as I was riding to work this morning) - it was more about the licencing of bikes for purchase. I was thinking more about providing a certificate of cycling proficiency in order to purchase a bike. There are lots of pitfalls with my proposed plan and I had shot myself down by the time I got to work. Still, I did think about the subject more than I would have before, so thanks for that @hillsideresident
Its nice also to see some sun today. Makes my trip to work a lot more fun.
