The message from "Will Reeve" contains these words:
It's one of the things I used to teach learners. Used to have a session where the game was to travel for 15 minutes without coming to a complete stop[1] which isn't easy round Watford. Didn't harf make 'em look well ahead and consider approach speed.
[1] Though of course I always included at least one junction with a STOP sign to make sure they were awake.
