The core issue is those red light cameras create a persistent database of who is where, which is then sold at a marginal cost to whoever wants it to advertise to/manipulate/track a population. Adding cameras everywhere invites a dystopian nightmare vs better urban design and occasional traffic police would solve the same problem.
"occasional traffic police" have proven ineffective at enforcing the law.
And biased humans deciding who to pull over is a lot more of a "dystopian nightmare" than cameras which eliminate those problems entirely https://www.pnas.org/doi/10.1073/pnas.2402547121
i grew up somewhere that had red light cameras, the idea that they are selling the data is BS justification for diminished state capacity to enforce something really important.
e: for those downvoting, please point me to a single case of a municipality selling red light violation data if this is such a real concern
Write the legislation so data is not retained/sold. Don’t throw the baby out with the bathwater.
