Re: Is the market voting with its feet?
UK Dept of transport releases accident data regularly. Originally the "Stats 19" forms were filled in by police whenever a personal injury accident occurred and included the location of the accident. Some of the required information was reduced during the 1990s I believe - to reduce police paperwork - but now enhanced datasets are freely available which has location, type of road, junction layout etc.
