answer:No way I would get in the car and let my SO drive after what just happened. Do you believe he reported the incident to his doctor and if he really did, do you think he reported it as you observed it? I will bet not. I’d contact the doctor, maybe by email and give your version of what happened since you saw it all. Your husband might be afraid and a little embarrassed, maybe he doesn’t want to admit the seriousness of this in order not to scare your son but it comes down to not being safe and not being fair.
