When people "get caught" out later than they intended with no lights (or as late as they intended but they didn't appreciate that the sun had gone to bed earlier than previously).
Anyway, spotted out of my front window a couple of young touristy looking types on BSOs getting a talking to by the police who were in an unmarked high-power Audi on London Road the other night well after the "lighting up" hour. Looked like they were given a lecture and told to push home.
There appeared to be quite a few polices around in patrol cars also. I assume that they were out trying to nab some of the obnoxious boy/man racers who use London Road between Jocks Lodge and Abbeyhill and also Marionville Road between Meadowbank and Lochend as a late night race track / "listen to how loud I can rev my engine and make it backfire" track.
