col said:but what is your definition of a safe distance for vehicles passing you?
If, at even slow speed, I could reach out and touch the vehicle, it has passed too close. In an ordinary lane the car overtaking should be comforably over on the other side of the road. If not, the driver overtaking has given less room than he would a car he's overtaking and has passed too closely. Practically, whether I'm in primary or secondary position, anything less than 1m from my outside elbow is murderously close, preferable would be 2m.
