Earlier quoted context omitted.
California's new speed camera pilot (AB 645) explicitly solves for this. Tickets issued by these cameras are civil penalties issued to the owner of the vehicle, like parking tickets, rather than a criminal moving violation. This means the tickets are just as constitutional as parking tickets. It also means penalties are limited to fines and can't impact your driving privilege or insurance. Hopefully other states can…
Consistent, low-impact enforcement is better at preventing unwanted behavior than the rare and severe but also capricious enforcement performed by human police. It can also give permission for unwanted behavior. Cf. the Haifa study, where the rate of late pickups increased when daycares added a fine. One explanation is the fine turned a complex moral obligation into an ordinary financial transaction.
I then moved to Amsterdam and became the biggest fan of continuous, always-on ANPR speed cameras. On some freeways, your car is recorded at certain checkpoints and EVERYONE driving over the speed limit ALWAYS gets a fine.
Why? Because they are properly implemented (only high-risk areas), very well communicated (tons of signage), consistently applied (no crying your way out of a ticket, no racial profiling), purpose targeted (you get a speeding ticket, not a bunch of other fines at the whim of a cop), and correctly incentivized (ticket revenue does not immediately go to the local police or city).
