More people on bikes means fewer cars. Coupled with frequent public transport means that your ambulance will not be stuck in traffic and that the bus that lets you not be homebound will take as long as the car you currently drive to get to the same places. And if you still need to drive, you will still be able to, it just won't be the only option available.

I live in a bicycle centered city and we have excellent ambulance response _because_ there is less traffic.

Disabled people have various mobility devices that go on the bike paths.

The quality of life is a lot better here.

The comment is an excellent exercise in reductio ad absurdum.
