Felix Salmon at Reuters notes that since Janette Sadik-Khan was appointed and started installing bike lanes, the number of cyclists on the road has more than doubled. This is good news for cyclists, but also for drivers and straphangers; if they are on bikes, they are not in cars or trains. Salmon writes:
The lesson of this chart, then, is that if you build bike lanes, cyclists will appear to fill them. That’s fantastic news, since cities with lots of cyclists are always the most pleasant cities to live and work in — even for people who don’t bike themselves.
