Comment: You can drive that day since most people that ride bikes to work still have a car. Or... they could catch a bus. Or wear a jacket. Or bring change of clothes. Or Uber / Lyft.  For most ppl that ride a bike to work, they could pay for Uber or Lyft on rainy days and still end up saving a good amount of cash every month.   

Agreed that cyclists need a safe place to ride.  Hence the need for bike lanes.  Most people cry about bike lanes because they're selfish and can't see beyond their own noses. In the long term, bike lanes will reduce congestion in the urban core by providing alternative means of commuting. It won't happen overnight, but to have it happen at all you need to start with establishing the infrastructure.
