It's worse than that. It's not even that "it's not expensive", it actually saves you money to take out lanes of traffic and making it into bike lanes, or running more and better public transport.

(1) More people biking and fewer people sitting in cars, not to mention lower pollution, mean you save money in healthcare for each dollar invested into bike infrastructure.

(2) In purely cold terms, killing e.g. a 30 year old represents a loss of productivity to the state in the order of millions.
