My daily commute from Bromley in Kent to Work (J2 of the M4) is a 20 mile journey, via Beckenham, Penge, Crystal Palace, Streatham, Tooting Bec, Wandsworth, Hammersmith, and up the A4 to here. There are 28 sets of Traffic lights, not counting pedestrian lights. 39 Left or Right turns not accounted for by Traffic Lights of which 14 are a turns into or across a main road. I did the complete journey feet up to the office car park. Didn't jump any Red or Ambers and only nipped out in front of one car. 5:45am to 6:30am mind you but still an accomplishment I feel.
