You can build infrastructure that encourages reasonable people to drive slower (an example I’m thinking of - you can remove priority rules at a junction and force drivers to negotiate it on a more ad hoc basis, which requires a lower speed to see what everyone is doing). You can’t build infrastructure which does this for everyone. Joe Twatface will just speed through that junction and let everyone else slam their brakes on.
A lot of features that discourage dangerous driving also prevent emergency vehicles from going at high speed.
On faster roads, these traffic-calming measures are generally undesirable also.
So: the methods are limited and have disadvantages. Traffic cameras can fill in the gaps.
If your traffic cameras are accessible to private companies who can misuse that data, that’s a problem that needs to be addressed in legislation. If your traffic cameras are accessible to police who are fundamentally compromised as part of a proto-fascist state apparatus, it’d be good to link your protests against cameras (which exist all around the world) to their use by proto-fascists (which haven’t co-opted the government all around the world, yet). And there are probably more effective ways of disrupting them.
