20-to-30 causes a step change in pedestrian outcomes, so no, the logical conclusion isn't 0mph. Also the average speed on 30mph roads before the changeover was around 20mph.

It improves traffic flow and reduces pollution too.

My only objection is that it's been applied in a somewhat blind way. Long sections of road with no houses and no reported accidents should probably be 30, or even 40mph.

Yes it is. If the only thing you consider is safety then 0mph is the safest. That's unarguable.

The point is that you can't only consider safety. There are other factors, but they are often deliberately ignored.

Well also we need to kill everyone so noone can die, the only logical conclusion.

If that's your best argument _against_ saving lives through road traffic controls then at least we know it's not wrong...

I hope your computer is completely unsecured, because if you cared about security you wouldn't even use the web.

I don't really see a step change between 32kph and 48kph.
