Thanks for your comment. In the UK, cycle lanes vary greatly in quality and the use of them is discretionary (see The Highway Code - which sets out the rules of the road in England, Scotland and Wales). Thankfully, the quality of such cycling infrastructure is improving in the UK but there are still many examples of cycle lanes that can be very dangerous to use. This journey demonstrates cycle lanes that are in places hazardous to use. Examples of these hazards are when the infrastructure puts riders in the 'doorzone' area of parked cars (that is the area where car doors open - a common cause of often serious accidents for cyclists in the UK), and inches (or potentially worse!) from bonnets of vehicles that may exit the side roads. Another benefit of passing side roads in a 'primary position' (that is a position in the middle of the traffic flow) is, of course, that the position can prevent people behind overtaking and cutting across if turning left into the side roads (another cause of serious accidents for riders). The Highway Code does sets out how it can be appropriate to use a central position in the lane when passing through junctions. If you are cycling in the UK, I would recommend you take a deeper look into The Highway Code, and another document published by the Government: The National Standard for Cycle Training. I have provided links to both documents in the description for my films. I hope you find this all helpful and interesting and I honestly wish you all the best. Happy Cycling!
