My current commute, from Crawley to Biggin Hill (by car, I’m ashamed to say) has a grand total of 5 traffic lights in 30 miles – and 2 of those can be discounted as they are immediately after another, and are always on green.
From a bike point of view, I used to cycle home at night, after playing snooker in the North of Coventry, to the South. The first 2 miles was an endless succession of lights, and I would always get stopped about 4 or 5 times – until I finally worked out the timing. I would get on my bike, outside the snooker hall, and wait for the third light in the distance to go green, before setting off. Pedalling like an absolute looney meant that I could get all of the lights on green – but it was very tight timing and very knackering.
The first time I managed it, I was very chuffed. (I was a LOT younger, then, so would probably struggle nowadays)
