I would expect fewer medical emergencies in a car than in some other settings. But people who've had a medical emergency are likely to get into a car to head to the hospital, and can then run into serious trouble. In particular it is common for people suspect that they may be having a heart attack, try to drive to the hospital, and then lose control on the way. This happens enough that standard advice from medical professionals for potential heart attack victims includes tips like, "Survive. Don't drive!" If you've got worrying symptoms, call 9-1-1 and NOT attempt to drive.

That said, the average ambulance ride in California is close to $600. So people have a strong incentive to try to avoid the ambulance, no matter how bad an idea that may be.
