The first two should never have let them go on. They should have escorted or called an ambulance.
The family car is not an emergency vehicle. If he had hit and killed somebody on the way, what would we all have to say then? She has a baby in a wrecked car looking at the dead body in the other car.
Maybe something like " Too bad that little kid on the street was run over and killed but after all his wife was having a baby."
