I only shared the EV magazine link as I saw fair amount of neutrality. I knew this was going to come up, conflict of interest usually does become a problem, but it looks OK here on this topic.

Its all about the Pareto's principle, no matter what it is. Find the Pareto frontier, and target it, but with proper assumptions as there can be more than 1 case targets. So that would look like, in no order:

an actual (and not for media optics) cutdown on speeds
less weight of cars without compromising safety
methods to hinder tyre particles from getting out at all (Tyre Collective built a device releasing next year, as these particles are electrostatic)
using less cars and more motorcycles
better and less toxic tyres
any tyre companies penalised, and tyre industry regulated for tyre pollution like how tailpipe pollution got regulated and successfully controlled
