Cycle lanes are convenient for motorists, not cyclists
1.11.09 by Buffalo Bill
John Franklin, author of Cyclecraft, probably the most authoritative book on riding a bike, reckons that
it seems that the first cycle paths were to meet the needs of cyclists in terms of comfort and ease of riding. Soon after road standards improved, however, the motive for building tracks changed to one of getting cyclists out of the way of motor traffic. Only in the Netherlands does there seem to have remained a pro-cycling reason for building paths. There is little evidence of cyclists demanding cycle paths for reasons of safety until the 1970s; indeed much of the opposition to using paths in earlier years was on account of the added danger present.
[from A History of Cycle Paths]
My own opposition to cycle lanes or paths, or super-highways, as the Mayor of London likes to call them, is a matter of record.
