Bicycles more dangerous than terrorism?

There are good reasons, in the three studies looking at how the terrorist attacks impacted on transport (NewYork, Madrid, London) - all locations had markedly different reactions (due to clearly explained cultural/infrastructural reasons) - in the case of London (unlike, for example, New York) there was no meaningful increase in car use.

Obviously differing patterns of usage are going to result in different fatality rates. I dont think that's in question. The methodology of the study could well be best practice - whatever. I object to the scaremongering by the author of the article:

"the 7/7 attacks could have resulted in a second wave of casualties on the roads as people switched from the tube to traveling by bicycle" closely followed by "214 extra casualties in the capital in the six months after the bombing".

Sounds like bike carnage.
