Can get them way cheaper used

I don't think you can draw too much from those statistics alone. How many accidents per miles driven? England has more developed, and better used public transportation, I'd be a lot less people are commuting 30-45 minutes every day to get to work.

Less rural and suburban areas, etc.

Not saying anything about slower traffic keeping right, not saying your argument is even wrong, just saying I don't think you can support it with those numbers alone.
