A few days ago comrade /u/InevitableSwing posted an astounding graph of automobile deaths per capita in different countries.
Obviously America was number one by far 
but what was amazing to me was that Canada's rate is nearly three times lower.
The countries are not that different in many ways 
.
Certainly things like aggressive driving and speed limits of course play a role, but I think the key is probably something a lot more simple: public fucking transit usage.
Example A:
USA
- Own car/drive: 85%
- Public transit: 12%
- Bike: 11%
Show
Example B:
Canada
- Own car/drive: 67%
- Public transit: 23%
- Bike: 11%
Show
So overall 18% fewer Canadians drive, and nearly twice as many take pubic transit.
A lot of our population is centred around the major cities that have decent public transit, and even some of the medium sized cities have decent bus systems too.
- Toronto
- Montreal
- Vancouver
I also feel like in USA there is a stigma around public transit usage. Like it's "dirty" and "for the poors".
I've only ever lived in BC so I can't speak for everywhere but I don't think those attitudes are nearly as prevalent here as they are down South.
Yeah it's a stigma. I've been at dinners with family and I'll get asked why I don't drive, like there's something wrong with me.
But really it comes down to most cities just not being built for it. No one bats an eye if you don't drive in NYC for example. Most other places in the US aren't like that at all though.
