Its good to have a post like this to liven things up. When people refer to "racing" i always take it as: either off the lights toast upto the speed limit. OR onto the dual carriageway (haha, a very apt name, maybe thats why its called dual!) from a slip road or roundabout upto whatevers a safe speed seeing which car pulls away most etc. I doubt that most people on here that post about racing actually swerve in and out of people dangerously, i think its more of a case of this: off a roundabout, if clear in front both boot it, the winner gets in front and pulls away convincingly, until theyve had enough.
Yeah its a bit dodgy, but no worse than say: not indicating when you pull into the fast lane if you forget, or cutting someone up when you come out of a sliproad onto a motorway - which occurs probably more often in normal driving anyway.
