Bad data
Bad Science deconstructs and rebuts some silly, fearmongering cycling accident statistics from a British insurance company:
“Mounting financial pressures have led to a surge in inexperienced cyclists taking to the roads,”say LV in their press release: “resulting in a 29% increase in road accidents involving cyclists in the past six months.” It’s topical, it involves death and fear, it’s dressed in the cloak of statistical authority: this is totally going on the telly.
The first thing to note is that LV were comparing accidents in the 6 months leading up to November 2008 against accidents in the 6 months prior to that. What these insurance geniuses have failed to account for here, we might reasonably suspect, is the well-documented seasonal variation in road traffic incidents, since fewer people cycle in winter. I shall not be buying shares in this insurance company.
