I guess it's less a worry about actively dying, and more a worry about being doored and breaking something. That's how the vast majority of people I know have been hurt, by being doored. There's just only so much you can do about that as a biker and most cities put it like road | bike lane | parking | sidewalk so the risk of getting doored or having a car turn out into you at low speed trying to get from parking to the road is just massive.
