I'm studying in a medical profession where I frequently attend to people in their homes, sometimes urgently (midwife in Canada). We are all required to have private cars to drive to people's houses and meet people at the hospital for births and assessments.

If the medical system would give me a free car to use for my profession that would be cool... But I'd also have to use it just like a private car because you can get called to a birth while grocery shopping since you're on-call 24/7 as a primary care provider.

Home care does actually take others off the road which is a fun bonus though. The first week of birth and postpartum assessments taking place in the home saves clients about 8 car rides which is great because riding in a car or driving during labour is no bueno and postpartum riding sucks. After a C-section you can't drive either. Even in a hospital delivery postpartum care occurs in the home which people find an absolutely fantastic experience. Those appointments aren't emergencies but there can be emergencies...

I know of one bike midwife. But that's extremely rare and all students must drive.
