I used to commute 10 miles to work and there's one long road in Portsmouth where the road is only narrow enough for a car and bike. The amount of times I got clipped because people didn't have a clue. Used to get really narked and hit one persons car after they did it twice. Can't avoid the worktime mood but I could ride along the coast line and up some quieter roads to go home. Took longer but I could swItch off.
On a funnier note my director had pannier and a plastic spike painted to look like metal with a small sign the said something like acme paint scratcher… He never had problems. Rather ironicthough that he apparently hit a cyclist whilst driving one day!!
