We are perfectly happy with a planning horizon of one: what is the next thing in your way. However, we are pretty unimpressed by this video which was sent to us of a car in Clifton who'se planning horizon was zero. When a car is coming towards you, you either do two things -commit at speed or back off. What you don't do is go alongside the bicycle at 15 mph with a car coming towards you at 20 mph, as that leads to an exchange of details and some insurance premiums, especially now that tax-dodgers are starting to carry cameras and no doubt willing to supply their videos as evidence.
If you are going to overtake with oncoming traffic, put your foot down!
