cycling in London compared to Berlin

Cycling in London is dangerous, as there are not many cycle lanes throughout the capital that are safe to use:
Cycle paths either appear suddenly and end as sudden as they appear, or they are next to parking bays for cars, leaving cyclists exposed to opening car doors across the cycle paths, or cyclists have to content with motorbikes, taxies and buses in bus lanes where -at junctions- there is a sudden left turn for cars / vans, and they veer off into the (previously safe-ish) bus/cycle lane to turn. I have seen cycle paths outside London that end to cross a busy, multi lane 'A' road with no traffic signals to protect the cyclist.  As a cyclist myself, I find it criminal that people like Cameron and Johnson harp on about the need to create and promote growth/business at all cost, detrimental to both environment and social responsibility, rather than looking at real people and cycling is one of them.

Power-assisted steering, the use of mobile phones whilst driving and sat navs have created new careless drivers.

In more aware countries, like the Netherlands and Germany, cycling is promoted, encouraged and nurtured.  Hopefully with news like the BBC  attitudes will change in London (the UK?)
