If you are saying that you support the construction of comprehensive segregated cycle paths then I am very much on your side.
Yes they can have their lane
It would be nice if motorists also kept to their lane, then. Too often I find my cycle lanes blocked by drivers who feel that the road was"entirely built entirely by motorists for motorists". I would also be happy to keep to my lane if it always existed. As it is, a lot of the time I’m left with no other choice but to join with the motor traffic as the cycle lanes just stop existing. In the UK it’s illegal to ride on the pavement, and I’m sure you wouldn’t want me to become another cyclist who just ignores the law for his own benefit?
It’s also important to note here that the UK now has the Hierarchy of Road Users, which explicitly states that the more vulnerable the road user, the more priority they should be given. Pedestrians have top priority, followed by horses, followed by cyclists, and then with motorised traffic at the bottom. It’s a very new development, and one that I don’t think has been tested in law yet, but it’s there in our Highway Code.
