Hospitals exist because CAT scan machines are expensive, and it makes sense for patients to drive to the CAT scanner, rather than the CAT scanner drive to the patients. Lather, rinse, repeat for every medical device. Sleep analysis tools, XRays, surgical tools and instruments, etc etc. ----- Furthermore, doctor time is expensive. It makes more sense for patients (who probably make less money than doctors) to spend their time driving. Not for doctors to be driving around making house calls like a maid or milkman.
