On: Pedal Me bans staff riders from wearing helmets for safety reasons

> There was one study about that, which was... not very robust science. It relied on self-report of the biker

Here is another study, where they measured the distance to overtaking cars with a distance sensor:

"A Trek hybrid bicycle was fitted with a Massa M-5000/95 temperature-compensated ultrasonic distance sensor with its centre 0.77 m from the ground, facing perpendicularly to the direction of travel and feeding into a laptop computer running MultiLab software via a MultiLog Pro data-logger sampling from the sensor at 50 Hz."

This study is done by the same researcher as the first. I applaud Walker for studying this, but both his studies have a sample size of one cyclist - himself, riding in one area of one country. [He did put a wig on sometimes, so maybe you could say the sample size is 2? ]
