Build and they will come miss mouse?
That is not proven at all. What did get masses of londoners on bike recently?
Tfl has been marketing cycling, adverts and free training for years, cycling has begun to look cool, people encourage their work mates and friends, drivers are making it easier by giving less hassle, c charge and other financial incentives like the tax break, slower speeds and road calming, bus lanes and bus driver training... Most of these getting people to use the current infrastructure. More stuff liken this rather than scaremongering and calling for impossible things like segregation on all major a roads
And not dressing like a total melt on commutes.
