Even with the caveats about limited data and untangling causation and correlation, the statistics are striking: the first year of a scheme in Wales where the speed limit on urban roads was lowered to 20mph resulted in about 100 fewer people killed or seriously injured.
In Darwin’s terms, the ‘survival of the fittest’ you referred to means something like ‘those most able to adapt to evolutionary change’.
In this context, your inability to adapt to a change that improves life for everybody, from the direct reduction in deaths, to reduced micro plastics (of which car tyres are something like 25%) makes you the unfit one. You are the idiot.
Let’s not ban all cars, even though it would be a positive development, let’s just ban idiots (to use your word) like you. It is clear by your attitude that you are not safe.
