Yes, they would. But they are not keeping present speed limits & sacrificing innocent children to car deaths there for the sake of the economy, as you falsely alleged. You provided no evidence that any government has ever done so or ever stated any such thing. In fact, BTW, many governments are taking multiple measures to reduce the number of deaths in car accidents.
You introduced car deaths with your analogy with the present COVID-19 crises, which you have long ago given up on arguing.
You also didn't explain the governments contradiction as per:
It's being alleged that governments are secretly conspiring to sacrifice lives to car accidents rather than lower the speed limit to 10 MPH in order to benefit the economy. Yet it is also being alleged these same governments are sacrificing the economy to save lives from dieing from COVID-19. So can't these governments make up their minds? Are they confused. Do they want to save lives or save the economy? Or is it that at least one or both of those allegations is wrong. Where is the evidence that governments have decided to sacrifice innocent children in car accidents in order to boost the economy? Where has any government ever stated anything like that?
If you can prevent traffic fatalities by lowering the speed limit, you would do it right? Makes sense right? We don’t lower speed limits because it’s a non-sensical approach to the problem. If we lowered the speed limits, large commercial deliveries would take 10x as long and that’s just one ramification. The impact of lowering the interstate speed limits to 10 MPH would be astronomical.
So, by not lowering the speed limits, our society and lawmakers are saying the risk is worth the reward. I can’t break it down anymore than that.
