> Motor vehicle crashes are a leading cause of death in the U.S.1, with over 100 people dying every day.

Motor vehicle crashes are slightly outside the top ten causes of death. Those 100+ deaths are coming out of about 9300 total deaths.

> The economic impact is also notable: for crashes that occurred in 2017, the cost of medical care and productivity losses associated with occupant injuries and deaths from motor vehicle traffic crashes exceeded $75 Billion.

Productivity losses are outside the scope of medical costs, but even if we include those dollars that's $75B out of $4100B in health care spending.

So I stand by my statement that it's a pretty small impact.

> American Society of Civil Engineers infrastructure report card says only 45% of the US population has no access to public transit.

And most of the other 55% still need cars.

You said "good subway systems and a walkable infrastructure" and that's what I responded to. We can go ahead and remove the word "subway", but the fraction of people with access to good public transit systems is pretty small.
