Londoners have taken to two wheels in record numbers to beat the Tube strike – but a significant minority of cyclists have been blatantly riding through red lights.An extraordinary two million trips are thought to have been made by bike on Monday, the first full day of an expected five-day Tube shutdown, according to London cycling commissioner Will Norman. Normally about 1.4m journeys are made by bike on weekdays.But the number of cyclists ignoring the rules of the road has also increased – a fact confirmed by video evidence gathered by The Standard on Wednesday morning – raising concerns within City Hall about the risk this poses to safety.We witnessed numerous occasions when cyclists paid little heed to red lights – or to pedestrians who were walking across their path with the “green man” illuminated.
