Most car journeys are short.
Most fatalities are caused by cars, on the drivers themselves and everyone else nearby. So less cars = less deaths in totality for everyone including the driver who ceases using the car.
So you are the problem yourself if you are not the solution of deciding to bike / walk or even if you car pool as each less car on the road is one less lethal object. Basically every driver who has an alternative is complicit in manslaughter. Those who not have an alternative have less chance of hurting others as the cars are further apart.
