Welcome to the age of nitpicking busybodies. Next month, he'll have a facial recognition system for dog walkers who fail to curb their dog.

Count me in as a "nitpicking busybody", though I'd hardly equate dog walking offenses with the kind of damage a speeding driver in a residential neighborhood can cause. Speeding in a subdivision is annoying to those who live in the subdivision -- it adds to the noise and makes it a pain to get out of the driveway in reverse -- but it's way more than that when you have young children, especially when they have disabil…

> Because of a light with poor timing that causes a back-up on the main road, our subdivision is used as a bypass during Rush Hour.

Your kids have been nearly killed on several occasions. Why are you projecting anger at some schmuck trying to drive home, but not standing in front of your town/city/county officials to fix the light?

If the light gets fixed, people stop using your subdivision as a through street.

Look around and try to find a civil engineer who does traffic management to talk to. This stuff is a science -- if you make the right demands, you'll get what you want and be able to sleep at night.

A pretty common sight around here (western europe) which seems to work pretty well are dynamic reminder signs: electronic signposts with a speed radar, which simply displays your speed in green if you're under the limit, orange if you're a bit over and blinking red if you're way over (using fairly bright led arrays so it's visible in most conditions) Anecdotally, it seems to work pretty well, drivers do slow down whe…

Anecdotally, I've heard of attempts to use things like that in the US, with the result that some people took it as a game to see how big a number they could get. One anecdote I heard told of a set of four of those signs being placed on the side of a freeway overpass, covering four lanes of the freeway, and people were observed to be swerving across all four lanes seeing if they could get a high score on all four signs at once.

Generally it seems you may photograph and film public property, assuming you believe Wikipedia.[1] [1] https://en.wikipedia.org/wiki/Photography_and_the_law#Public...

This wouldn't fly at all in Germany. If your surveillance camera films public ground, even if it's not the primary object being photographed, you're acting illegally. If, for example, you're trying to monitor your front door to catch a potential burglar and you can see the pavement and the people on it on the video, that's not allowed. You won't be able to use the footage in court even if it shows the burglar clearly…

There are numerous webcams online showing German public spaces, streaming live and offering access to archived views. Are these illegal, or is there some kind of exception for when the surveillance is for public broadcast, or what?

You're also relying on the reflexes of someone who is sitting in their car literally watching traffic for hours at a time. The state police can use radar so the floor goes down to 6 over the limit if they are enforcing.

So now you're telling me the police check speeding by eye . Jeepers !

It's literally "start the stopwatch when the front tire hits the first line painted on the road, stop it when the front tire hits the second line (or some other predefined immobile point), and look at a chart to see how fast they're going."

Usually radioed to a second car down at the next intersection.

Same in France.

About webcams, AFAIK, the exception is either because people and car plates cannot be identified clearly for the image quality (and frequency) is low, or because they asked for a special authorisation.

One solution is dynamic speed bumps that measure the speed of vehicles, and then lowers if the vehicle is speeding. https://www.youtube.com/watch?v=eRHphB-YqN8 https://www.youtube.com/watch?v=KxpvwKiOpag

Great way to damage your suspension

There are signs posted about dynamic speed bumps, and the speed limit. Speeding anyway is optional.

It's been installed in a test location for years, and is being deployed in several cities in Sweden at the moment.

No wonder people think the moon landings were fake.
