Gosh, until the mid-90s (after which one of my knees went) I cycled thousands of miles a year, for several years in just about the busiest urban area of outer London, then in rural Devon and Cornwall for four or five years after that. My daily commute was 16 miles a day (return!) in London and 22 miles a day in the Westcountry (each daily return trip involving 1400 feet of climbing). Not once did I ever break any rule of the road, nor did I ever have any altercation with motorists or pedestrians. I think that most cyclists are environmentally conscious and would not wish to harm or inconvenience pedestrians. Of course, there are always a few. It's amazing how so many people, including two or three here, jump opportunistically on cyclists, who, as a genre, are mostly very responsible. Cyclists don't create air or noise pollution and are not using fossil fuels. Remember that at least. And yet, when I mention that the vast majority of dog owners can't control their dogs and fail to clean up after their pet noise machines (come to Bude if you don't believe me), I get shot down by the "it's not my dog" brigade. I know that the odd cyclist can cause harm, but that pales alongside the health hazard that every dog at large in our streets potentially causes.
