This type of whining about slippery slope hypotheticals is ubiquitous in these discussions, but it's not very compelling up against the current reality of 40,000 unimaginably violent early deaths every single year in the US alone
I’ve seen a number of cities find the authority or political will to increase the number of automated speed cameras. This suggests (while not a complete complete solution) a real step in the right direction
Once that's done the changes can roll out whenever there's maintenance or road widening going on. This is for example what Florida is doing to push for a comprehensive passenger rail system and it's what other countries have done to make their roads and streets safer and more efficient as well. So it'd stand to reason the same principle would work at state and local levels in the US for this as well.
The only real argument against it I could see is that it'll take too long but 30-50 years really is nothing for widespread infrastructure improvements.
I disagree. The economy depends on the rivers of money that flow through the roads. Roads dispense communication, goods, labor, et al, over the vast area that is the USA. 40k deaths, distributed across the US, is a good deal.
On the other hand, I had great expectations for companies that wanted to provide a solution that's safer for a profit (robocars). A handful of people died during the development, and it's rejected outright by large portions of the population. So here we are.
Of course I was being mildly hyperbolic when saying we could solve speeding with technological enforcement, but I genuinely believe it could make a massive difference and lead to a significant quality of life improvement for most people. For those with the need for speed, build more tracks. But we should stop normalizing reckless behavior on our shared roadways. There should be an expectation of safety and we should maximize traffic flux while minimizing traffic injuries and fatalities.
Changing behaviour with a penalty isn't terribly effective unless enforced in such a way that it is incredibly privacy-invasive, more effective is changing the layout of the streets. But I wouldn't be sure that that is easier to fix on the pedestrian side than on the vehicle side.
You cannot eliminate risk, stop people from taking risks or stop people from dying. You say callous and I say practical. We all make tradeoffs every day, which has elevated society from subsistence existence. eg Every person doing physical labor, every doctor pushing diseases to be more resilient.
Will you step up when it’s your turn?
People just run out of shits to give at some point, and do what is easy.
It's really macro-economic and social inertia. Those sedentary folks have also convinced themselves they LIKE IT, and there is room (and real economic incentives) in the US trending in those directions. Like low property prices in the 'burbs, cheap gas (by global and economic standards), etc.
