The AA would be better employed asking why there are 2700 deaths a year on our roads...
That is a perfectly reasonable point, but the AA may not see it as a task that falls to them.
The Auto Industry (tugged by glacial legislative change and to an extent public opinion and the market) has made some effort in protecting people hit by cars as well as the occupants.
We are a Lightyear from the perfectly justifiable rage of Nader. I'd rather not be hit at all by a car, but better today's cars than the spiky, steel-bumpered, ornament-adorned beasties of yesteryear.
Today it is harder to get a driving license than it was 20 or 30 years ago. That is a good thing.
Today's cars are heavier (bad thing) but they are designed with safety more in mind than they were 20, 30 and 40 years ago.
Roads are still more dangerous than they ought to be, but as shared-use environments they are conceived with some thought to pedestrians and cyclists. They are not perfect, but better.
The AA, SMMT et al have an agenda in conflict (or at least not in harmony) with that of many cyclists.
Casualty figures for UK roads are not great. But they are seen by most adults as somehow acceptable. I doubt there is anyone alive who hasn't lost a friend or relative in a driving or riding incident. Some will have lost quite a few. It is a beastly business.
Nonetheless, the figures are spread out over a wide geographical area and a long time period. Somehow we (collectively) have made the decision that we can live with these losses.
A media campaign highlighting comparisons with losses in an aircrash/hurrican/ terrorist attack would garner interest for a day or two. Then a Panda would be born in Berlin Zoo and we'd be off again.
Regrettable or not, that's how it is.
