How times have changed

It's only a short time ago when the "no horses" sign at the entrance to this subway was a "no cycling" sign. These days, when cycling is suddenly the in thing an encouraged it's fine to ride through this. I'm not complaining as it's a very safe way to cross this busy road but why is it ok now but not been ok for the previous 30 years??
