It's worth bearing in mind that drivers are already speeding in 30mph zones so therefore are likely to be speeding in 20mph zones too. Not anyone on here of course, because we're all law-abiding and socially minded members of the community on CCMB.

Personally, I can't wait for smart limiters on vehicles so you won't have any choice. AI is going to be so much better at this stuff than you are. You won't even need speed cameras because of smart data logs. All this stuff is available in motorsport right now (Endurance racing & F1) and all the current bells and whistles come from team and manufacturer's innovations.

Even the World Endurance Championship is using biofuel this season.
there is also research that shows the 90% death rate at 40mph is based on an 80% death rate given by the DofT which might be exaggeration, thanks to modern car design you can find 30% survival rates at 40 , but when we are all microchiped we will know the truth
