BBC did an interesting article on this topic. The concept of jaywalking is built on the assumption that roads are primarily for cars. There is certainly a legit safety issue; but the assumption that all other modes of locomotion are secondary nuisances on the road is a construct of the auto industry.
On the topic of facial recognition to fine jay-walkers; it seems like just one more reminder to the Chinese citizen that the government is watching. Oppressive and ready to pounce.
On a day such as Memorial Day in the US to come across this piece (which is excellently written and researched) is a sobering reminder of the cost of freedom and the threats it will face in the future.
Tech like this, no matter how well intended lends itself to abuse and misuse. While politics and procurement are best maintained by a firewall separation; I find it increasingly difficult to remain objective.
I’m not buying that the true reason for this system is to reduce jaywalking.
the fact that motorists have “scarcely a care for passing inconveniences such as pedestrians...” and that crossing “sometimes feels a bit like stepping out in front of a firing range,” should be deterrent enough.
and jaywalkers are not ashamed anyway. everyone sees them.
Update: there was some controversy in the PRC city of Taiyuan after children's faces were displayed (in full detail) on a "board of shame" at a local intersection (see screeshot below). Local media asked police whether this was appropriate, but the police department's response was that kids/adults get the same treatment.
