"We would be potentially forcing motorists to drive at the speed of cyclists when there isn't the recommended space to overtake."
You get these muppets on twitter who respond to operation close pass tweets with, "What should I do if there isn't enough space to overtake safely?"
People reply - sometimes politely, sometimes not - by pointing out that dangerous driving is dangerous driving. And, if you can't overtake safely, you can't overtake legally.
Turns out Cambridge police are those muppets...
