Bicycles more dangerous than terrorism?

The article implicitly attributes 214 additional road casualties to the 7/7 attacks. The article only mentions one alternative form of transport prior to this, its one and only statistic.

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.
