Mizuka just bought a CellStar SKY-230DL radar detector. It's amazing. It has a GPS receiver built in. It knows where speed traps are and lets you know 2 km before you get there. (In Japan, we have automated speed traps that take your picture and send you the ticket in the mail.) It also lets you program new information. For the tunnel exit based traps, it lets you know before you enter the tunnel, etc. It also detects police radio and figures out whether they are heading towards you in the same direction or on the other side of the road. It has a variety of special warnings for stealth pulse radar detection, etc. These things have come a long way since the last radar detector I bought. This is a good thing since we're going on a road trip today.

The last time I got a speeding ticket, it was on the way back from the airport. I received a picture in the mail and had to go to the police office. The funny thing was, they suspended my license and then the policeman pulled a map out and showed me where the speed trap that got me was located. He warned me to slow down next time I passed it. ;-)

That is sexy hardware. God bless tehcnology!

It makes sense that Mizuka-san bought it. Moblog tells ;)

yeh We're in a hurry...
don't Crash

Speed kills!!!
Don't try to take something like this in France, they will take your car away.
I thought Japan was a civilised place. To allow people to use radar detectors is giving them more ammunition in their criminal activity.
Shame on you!

Its use of police radio signals has a lot of room for improvements. Throw in wireless sniffer and top it off with P2P capability to cover the whole city in real time. Hey, you got a Must-Buy for criminals and terrorists. Interesting.

Are you going to shoot on through the toll gates without paying the highway tolls as a protest against the perpetual amakudari highway construction gravy train?

Speaking of gadgets, when are you going to get an iSight and review it for us?

So when you get a photo of your car speeding in the mail, do you send a photo of cash back?

Andrea: Japan, civilised? *pshaw*

I can see how this device could be abused. I'm being very selfish here. I speed, but I don't drive recklessly or drive drunk. The speed traps in Japan are often set up in places where the naturally safe speed exceeds the official speed limit. The speed limit on most expressways is 80km which is quite slow when you are on a deserted highway going straight. Another thing is that many local governments set up speed traps to intentionally catch "outsiders" when all the locals know where the speed traps are.

This device is so good that I can see how it could be abused tho. There is a web page to upload any new speed traps you find and you can buy updates. On the way to the inn, it found 2 induction coil sensor triggered hidden cameras, 3 traditional radar cameras and 2 police cars.

What happens is they send the picture to the owner of the car based on the license plate. The driver of the car is then supposed to go to the police station with the ticket. You're usually quite nice to you. I once even had them thank me when I paid the ticket...

This is a fine line I guess. My respect for traffic law is quite limited, but I also believe in safe driving and realize the danger that bad and reckless driving pose to others. I wish there were a way to dispute unfair speed limits or unfair "traps".

Another thought. If similar devices get popular enough for most cars to have one, the city government can lay a whole network of induction coils, radar and police radio signal generators to control traffic.

"Look, traffic on route A5 near Sushi Road is slow, lets turn off the signals there."

While I like new gadgets for neato factor as much as others, I really enjoy the changes they might make to individuals and societies.

The expressway we came back on had induction coil cameras ever few kilometers. We weren't speeding, but every time we passed on, the detector told us another one was coming up. We must have passed half a dozen cameras on the way back.

The system also noted "N-System" cameras when we passed them. N-System is a Japanese police camera network that does OCR on your license plate and tracks cars. The purpose is supposed to be to track criminals and stolen vehicles. From a user perspective, I don't really NEED to know when I pass an N-System camera, although if I were a criminal, this would probably be very useful. On the other hand, it's nice to know that kind of camera it was that you just passed. I think the possibility of abuse of the N-System is a huge risk to privacy so I guess it's nice that our new toy reminds me every time "they" know where I am...

All these cool thoughts from just one little gadget...

Actually, Andrea, there's no evidence that "speed kills".
The fatalities statistics on the non-limited sections of the German Autobahns are much lower than those in repressionist EU countries, for example. This fact is conveniently overlooked by the traffic regulation fascists.

I assert that it is possible for a careful and responsible person to drive, after considering e.g. visibility, traffic density and weather conditions, at a much higher speed than allowed by law in most countries.

Besides, from a traffic safety point of view, I find it inconsistent that septuagenarians or sleep-deprived truck drivers be subjected to the same speed limits than, say, an alert, agile and well-rested twenty something.

In the real world, though, open roads are a shared asset, and I would be more than willing to surrender my ability to speed if effective electronic measures overriding my car controls also meant that e.g. drunk driving or speeding in residential areas by irresponsible drivers was made impossible.

Impressive device. Other than speed traps, does it beep only when you're travelling faster than the speed limit? I thought that would be the killer feature that makes it worthwhile to add GPS to a radar detector.

I agree with Andrea. If you do have some kind of accident, you're going to have a better chance of surviving if you're going slower. It's also less wasteful of gasoline.

In various places in Texas there are speed trap roads with sudden, inexplicable drops in the speed limit. In those cases I agree with Joi. But as far as 80 km being slow on long straight roads, just set your cruise control. Yes, it's hard to maintain a speed of 80 km on a boring stretch of road if you have to concentrate on the speedometer, but it's easy if you set the cruise control.

My way is simple. Slow down when the fast cars ahead of you slow down. I found that most fast drivers know when to slow down. I just follow :)

In the UK they have these new cameras that read your number plate at one point and record the time you passed it. Then in a mile they do it again and work out your average speed... try building a gadget to let you avoid that one... [without the rotating number plate please!]

I'm not a local here or anything,.. but just to fuel the fire a bit:

These guys sell a few products that make your license plates unreadable on a camera but look normal to people. I've never used one, but I buy the principal there based on anyway.

Just for shits and gigs you might also want to think about intercepting the radio signals used by the police to send their locations back to the dispatch center. A willing person could build a system that showed all the police on a map in your car...

Take a look around, you might be suprised how much *useful* information is available to those who might like to build such a system

They should open up the GPS-based system and set up a worldwide open-source network to warn people of speed traps who have GPS and laptops.. (you dould download the list of local traps each time you connected to the net as you were traveling)

That part of this system is independent of radar/radio sniffing, so it could work.. And add to the efficacy of the system for all who used it..

Where is the cheapest place to buy one of these marvellous radar detectors?

Living in Quebec Canada i wish to know if this unit is undectable by
the new VG-3 called Spectre shown on this site :

http://www.policeradar.com/RDD.htm

Also what is the price in us dollar for this unit.

As Canadian toby wish to know if this unit is spectre-undetectable so do I.

Does anybody know if this unit is made without local oscillator that means, it is not superheterodyne detector. The most wanted detector in canada and here in Finland is direct-conversion detector that not emit oscillator waves which are detected by that goddamn Spectre.

In Finland detector users have lost thousands of detectors and get massive tickets after that when finnish highwaypatrols get spectres!!!

If you have any knowledge about these units whitout LO or with different LO-emission than US-made detectors, please contact my e-mail. Thanks.

speed kills someone said does it f*** speed doesnt kill!!
with all the unrealistic speed limits and speed traps everywhere its about time we had
some technology like this to fight back.... i'm sick and tired of doing 40 mph here in the uk when only a week ago the speed limit was 70 mph..... and some how they cant just drop it overnight and of course a speed camera van operates on this road!

Two years ago I bought a Vehicle Speed Alarm from Rx4Speeding.Com, a US company. This device will alert you when you are driving over a speed limit you have set.

hello i saw this and i was wondering if this device would work in America. if it does can you please give me some information. thanks a lot
