Applying Covid Approach To Traffic Fatalities

If we want to eliminate ALL traffic fatalities
it's as easy as one, two, three

Reduce Speed Limit To 5 kmh
Problem Solved!

Sound ridiculous??

It is the same logic that has been applied to the current covid crisis and it would eliminate ALL traffic related deaths. Of course, our world would grind to a halt, much like the result of the panic response to covid.
