Laser braking; I wonder if this works for cars behind motorcycles...

[bhendron]

Also why only up to 50mph...?

"Laser braking on cars 'could help save thousands of lives': Call to make system that can slow vehicles from up to 50mph compulsory on all vehicles"

The AEB standards are written for radar based systems, laser systems seem to be restricted to these standards so far. There are three types, AEB City for up to 32 mph and AEB Inter Urban up to 50 mph and pedestrian.

There are considerations for all systems based on traffic clutter from many systems, traffic from oblique directions and ambient lighting conditions interfering with laser. Radar for cars needs to be able to reach out far enough to determine closing distances at 50 mph but not be interfered with by other traffic signals which caps useful range.

Hmm, according to this, it will work on objects as small as pedestrians, so I guess that would cover motorcycles.

So if you believe the sales puffery in the ads you can be a total bonehead and back out oif your driveway without looking and the car will stop itself when it "senses" a car ripping down the street at nominal driving speeds.

Yeah... I remain cautiously pessimistic.

I can also envision this thing being a total PITA, having your car stop for no damn good reason all the time because it "thinks" something is headed your way. And then if the nanny doesn't stop the car in time and you run someone over, who's to blame. The manufacturer obviously, because you paid money foir this feature to prevent that.

Personally I think I would prefer that people looked wherever the hell they are going and stopped relying on technology to cover their inept asses for being crappy drivers. Then take some personal responsibility for your own actions.

And get the hell off my lawn! :nono:

Hey, some systems will try to alert you first with an alarm, if you don't respond it yanks on your seat belt in an effort to wake you up. Still failing that the system will brake for you.

Kids from my era: Hide behind bushes, when a car approaches throw snow balls at cars.

Kids from today: Hide behind bushes, when a car approaches take a string with a ball of aluminum foil attached and pull the ball across the road and watch the car automatically slam on the brakes.

I want the system that detects when a cell phone is in use and zaps the phone with lasers

I like the idea of a ball of aluminum foil. Maybe it would work to slow down drivers on a narrow residential road with diagonal parking on one side, a kids playground on the other side and lots of pedestrians. Nothing else seems to help some drivers figure out that 39 mph is too fast for those conditions.

Nah, today's kids will jump out in front of the cars themselves. It'll be the new stupid thing to put on YouTube.

I've noticed that I'm seeing a fair amount of apparently false positives on my new Radar/LaserDetector from late model high end luxury vehicles. I'm thinking some may be from these types of systems. Festar and I experienced similar phenomenom this summer, meet car miles from anywhere or anyone and get detector alert with no apparent radar detector in the other vehicle.

I know from driving several that some of the models I've encountered have optional cruise control systems that automatically slow you down when following another vehicle.

 

[Fred W]

I noticed the same thing on our trip out west, and a lot of them appeared to be coming from tractor trailers, since they were the only vehicles within line of sight sometimes. Which leads me to believe they may be instituting some kind of blind spot detection systems that emit K band radar.

I'll be in the market for a new RD in the coming months. I'll have to investigate which ones are able to filter that crap out because it really creates a lot of "wolf" crying from the RD which makes one less likely to respond to a real alert.

 

[bigjohnsd]

I don't mind "wolf" as long as I learn to recognize when I'm near the wolf's den.

For me the RD is just a piece of the puzzle, eyes, situational awareness, where it would be advantageous for a radar or laser trap.

I like the Adaptive TPX 2.0 system

I think there's a problem with this type of automation, in that it does not go far enough. Some drivers, (OK, quite a few drivers), just don't seem capable of the sustained attentive effort required. I often suspect this ineptitude has been exacerbated by such technological advances as the automatic transmission. A stick requires additional interaction with the vehicle, and therefore with the act of driving.

Fully robotic cars would be a boon.

There may even come a day when there are fully robotic motorcycles.

I'll accept that, under the condition they also fly.

Fred some commercial vehicles are using the Eaton Vorad. It has blind spot detection and helps keep following distance using audible and visual alerts and automatically keeps following distance with the cruise control. It also has a lane guidance feature to maintain lane position.

I had that radar, I called it "fog radar", (California central valley was home) installed in my brand new (1998) Freightliner Century class semi. about 2 years later they had the system wired in to the cruise control. It couldn't actuate the brakes at that time but is sure could adjust your speed. So, yes many of the semi's now have an active radar system on them. The blind spot detector only alerted if the right turnsignal was on, so I think it was only emitting signals when the turnsignal was on.
