Generally, information recorded (or maintained by, and often if contracted through a third party) by a government agency is made public if that state's public records law does not consider it to be private. "Private" is usually defined on a state-by-state basis. Every state has a public records law.
Some states consider license plates to be private, while others don't. Foe example, Illinois considers license plates private only if it's associated with other personally associatable information.
Aggregate or redacted information on accidents might be accessible in the case of privacy exemptions. Unless it's all on paper, which dramatically complicates things because of the efforts required to review/redact where needed.
In other words - if an agency has access to records on traffic incidents, it's probably accessible.
Around here there would be a public record of an accidents location if it was big enough to bother waiting for the police, although the public portion of that would not be tied to my name or license plate. Announcements (by authorities) on larger accidents mostly contain maybe an age, gender, and generic vehicle information. Other than that only the two insurances involved would get more data.
The only thing I could think of that made more information public might be lawsuits that could occasionally result from an accident but I'm not sure on how public those currently are. Our news around here usually refrain from naming people in reporting anyway if it's not too relevant or it's a public person anyway.
If there's a police report, then of course it's a public record.
In the EU, the "e-Call" system is being rolled out which mandates that the car automatically phones home in the event of a crash: https://en.wikipedia.org/wiki/ECall
>But given the number of vehicular deaths...
Ah the good 'ol "my principals go out the window when $emotionally_loaded_topic is involved."
Nobody, not the insurance company, the DMV, nor the people debugging the software in prod deserves access to ones data without express and informed (i.e. not a million word eula nobody reads) consent. It's no different than data generated by a cell phone or smart blender
Anyone worried about safety can find an external way to monitor that.
There are plenty of cases where we can and do make exceptions to personal privacy for public benefit, under certain guidelines. E.g. medical data is one of the few things that's actually private by law in the US, but we still find way to make aggregate data available for epidemiological studies. Location data is absolutely sensitive data, but there are valid reasons to make subsets of it available for the public benefit.
I'd be more likely to agree if traffic laws weren't already such an arbitrary garbage fire of selective enforcement.
Though assuming this data was not networked and belonged to the individual (can still be used as evidence is court), a black-box is probably a good idea.
Or we could spend a small fraction of the war on drugs on more traffic cops and save many more lives than the war on drugs has. Driving is extremely dangerous, and there is a significant number of people out there making it even more so by tailgating, suicide lane switches, and excessive speeding for the road conditions.
Otherwise, I kinda agree. Eliminate drunk driving and make it so everyone is wearing a seatbelt, and the fatality rate would drop by half.
Yes, driving has gotten much, much safer over the past few decades, but it's still the most dangerous thing we do on a daily basis.
Corporations, on the other hand, have no such need.
It's also difficult to overstate how much value universal transportation has brought to the human race. Maybe more than enough to justify the surface area dedicated to it.
But given the number of vehicular deaths, I'm all for having authorities access blackbox-style data like pedal state, acceleration vectors etc. that some controllers already keep around. If you are operating a 100 kW machine in public, how you do it isn't a privacy concern.
