I SEE my suggestion about taxing and registering cyclists has caused people to tell me that it has been tried (usually overseas) and it has not worked.

My reply to this is that this was in the days when computers weighed a ton and occupied a small house so let us try again. After all, civilization would not have advanced very far if we had given up at the first attempt.
