I would like to see some valid research on the subject before I let my anecdotal evidence decide me. I probably notice the bad scooteristas more than I do the sensible bikers, but some solid research is long overdue, and that is all that Regulator is suggesting, as far as i can tell.
There were three Tfl reports, first one - inconclusive more data needed. Second report after taking on board the criticsm of the first, was given to TFl and members on the comittee yet never published used better research methodolgy. The third report that was published by TFL is similar to the first report in it data and research methodolgy.
On the second reports finding London borough of westminster has allow motorcycles in bus lanes as does the London Borough of Kingston. But the findings from the other areas, such as bristol to name one of many, are not acceptable as comparable data.
But hey when someone quotes their qualifications as to why their view of a report is best, I take that as an inadequacy in themselves as they never seem to wonder the qualifications of the person asking the question. By the way I have two doctorates, one from and italian Universtiy and one from and English one, so know nothing about research methodolgy. That was the first personal comment, after your few. It is also the last .
