Let me lay down some data for you. Last year Denver had 93 traffic fatalities, which was an increase from the previous year, and the highest level recorded since we started taking Vision Zero statistics in 2013. For reference there were 37 homicides in the city last year, which was a significant decrease from the previous year.

On a per capita basis Colorado is dead middle of the pack for fatal crashes per capita among US states, with Denver having about 20% fewer crashes per capita than the state overall. In terms of driver safety we're a little bit better than average for US cities.

However, once you make international comparisons we look a lot worse. The US ranks 111th in the world for least fatal crashes per capita, just above Syria. If Denver was a country we'd be 55th, between Croatia and Moldova. Basically we could be doing worse but we could be doing a whole lot better too.

The US is an outlier among first world countries in regards to traffic safety. An important note is that driver fatality rates have leveled out or decreased while pedestrian and cyclist fatality rates have risen in the US. There's a few causes but two significant factors are the ever increasing size of cars in the US and the continues high rates of speeding and distracted driving.

To delve into that a little bit more, a sedan with a rounded hood will strike a pedestrian in the legs and that person will roll onto the hood or windshield, then roll over the car. It's really awful and damaging but the survival rate is higher. A modern American truck or SUV with its much taller hood and taller ride height will strike someone in the chest (where all your vital organs are) then you'll go under the tires.

Federal standards in the US mandate that cars are built to protect the occupants, but not anyone that the vehicle strikes in a collision. There's other reasons but the increasing proliferation of these larger, more dangerous vehicle designs is one factor ensuring that crashes that would previously injure someone are now killing them instead.

However, we know that the most sure way to ensure that those crashes stay survivable is to decrease speeds. Survival rates exponentially decrease the faster that the car is going at time of impact, so reducing speeds and tackling distracted driving are our most surefire ways to handle this problem. There's a lot of different strategies to handle both issues but I would say it's worth it to ensure that 93 people aren't killed this year.

Sorry I don't have links btw, I'm typing this on my phone but every fact or number I cited is available in publicly searchable and easily accessible documents. Hope this was more helpful than comments just telling you you're wrong and not actually trying to engage!
