What is it about walking/driving/riding a bike?
Is it the unconscious act of concentration? The manoeuvring of self or vehicle through the chaos of traffic while your mind travels on a completely different terrain?
Is it the fact that you're all alone in a sea of humanity, faces you see unseeingly, faces you shall never see again?
Is it the moment of privacy, the pause in your schedule where you are forced to do nothing else but cover a distance?
Is it the fact that you are exposed to sun, sky and wind, dusty roads and restless feet, noise and the collective commotion of a city's frustration, ambition and desperation?
Is it the movement in your otherwise non-adventurous life?
Is it the rhythm of your footsteps, the routine of moving wheels, the procedure of the traffic signal, the unspoken order followed by strangers together in a moment of mundanity?
Maybe it's just that it reminds me so much of life itself.
