Yeah, that got to me. I spent a good few minutes wondering whether I'd physically assault a police officer who was preventing my wife from getting to the hospital.
Pretty sure in that situation I would just not pull over, and continue to the hospital. I'm sure there would be consequences to that (for me), but a bunch of emergency room personnel ushering a woman in labor into the hospital would hopefully override anything a cop was trying to do to keep her out.
I wonder if it would be useful to call 911 in that situation. Even though the authorities are involved, getting some more people aware of what's going on might put a stop to the nonsense.
Realistically the correct course of action is to call the non-emergency dispatch or call 911 and immediately inform them that this is not an emergency and to inform them the situation.
"An officer has turned on his lights and siren on Highway #101 but I am <continuing to the hospital>/<driving to a public/lit/safe location>."
Dispatch should contact the officer, relay information and they can return the details to you. Whether or not the police take offense and make your life hell is another story.
Many, many people do stupid things they'll regret when they're angry. This isn't "internet badass" bluster, it's a simple assessment of your own likely reactions.
It's been more than ten years since I've been provoked to physical violence, but I do worry about being caught in certain situations.
