Without being clear about what replacement transportation mode you expect to substitute for cars, it's not clear to me that your point is being proven. If we replaced cars today with walking or the current state of public transport in the US, I think my life is made vastly better by the near-ubiquitous presence of cars, even if it means I have a lifetime risk of just under 1%.

If cars save me just 10 minutes per day, my life is improved as compared to the just under 7 minutes per day of life lost to the lifetime risk of dying in a car accident.

We normalize traffic deaths because there is a net benefit. Just like we normalize other negative outcomes from overall positive-utility activities.
