re cyclists overtaking on the inside and how much clearance they should give - as it's about safety, the two situations are not comparable. a car overtaking you with less than 1m to spare is hardly the same as a cyclist doing the overtaking with less than 1m to spare.
it's like (reductio ad absurdum alert) comparing a train passing you with less than 1m to spare, and you walking past a train with less than 1m to spare.
