Discussion Overview

The discussion revolves around the connection of a motion sensor to the brake line of automobiles, particularly in the context of safety technologies such as automatic braking systems. Participants explore the implications of such systems, their effectiveness, and the broader acceptance of technology in vehicles.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants inquire about the specific motion sensor being referenced and its role in braking systems.
  • One participant describes city safety braking systems, suggesting they provide braking assistance through a laser and involve an accumulator and actuator in the hydraulic circuit.
  • There is a debate on whether such motion sensors should be mandated in all vehicles, with some arguing against the imposition of technology that they perceive as unnecessary.
  • Several participants express strong opposition to automatic systems, emphasizing a preference for manual control and expressing frustration over perceived technological overreach.
  • Others argue that assisted braking and collision detection represent a logical evolution of safety systems, citing historical acceptance of technologies like airbags and ABS.
  • Concerns are raised about the effectiveness of ABS, with references to studies suggesting it may not provide the expected benefits in certain crash scenarios.
  • Some participants note that panic during emergencies can lead to improper use of ABS, potentially resulting in accidents.
  • There are discussions about the balance between automation and driver control, with some advocating for more manual options in braking systems.
  • Participants share personal experiences with ABS, contrasting older systems with modern technology and expressing varying levels of satisfaction.

Areas of Agreement / Disagreement

The discussion remains unresolved, with multiple competing views on the necessity and effectiveness of automatic braking systems and ABS. Participants express both support and skepticism regarding the integration of such technologies in vehicles.

Contextual Notes

Participants reference various studies and personal experiences, highlighting the complexity of the topic and the differing perspectives on safety technology in automobiles. There are mentions of outdated studies and calls for more current data, indicating a lack of consensus on the effectiveness of ABS.

Who May Find This Useful

Readers interested in automotive safety technology, the evolution of braking systems, and the implications of automation in vehicles may find this discussion relevant.

Most new cars store all that info from the last few seconds of driving before airbag deployment.
There's currently legal haggling over whether insurance company and liability lawyers should get access to it.


I have a feeling that this will soon be mandatory.
edward - that thing is a cellphone ? Sounds to me like they've automated the speed trap. Next logical step after traffic light cameras.
Ask a lawyer if accepting that thing is a voluntary surrender of your fifth amendment protection .

I have a similar widget to that one except that I use it to monitor my car's performance, efficiency, and how everything has been performing - it hooks to my phone over bluetooth, and it's a fantastic way to keep track of my car's behavior over time. Mine also doesn't have a cell phone or GPS connection at all - it's purely a way I can monitor my car. All those sensors, electronics, and the like can be good or bad, it all depends on how you use them.

In my case, the data logging can show me how I can drive more efficiently on the street, and it also let's me track things like engine temperature, shift points, throttle position, and the like when I take my car to the track. Having that data is a fantastic tool for improving performance and efficiency, and for seeing when something is starting to go wrong.

As for that thing becoming mandatory? I very much doubt it. There's no safety benefit, and the cost would be substantial. They couldn't generate revenue either, since even if one of those devices recorded you going 150mph through Nevada (or something like that), they can't ticket you without proof that you were the one driving the vehicle.

Well, don't let your car report itself speeding in Pottersville.


Civil Forfeiture (In Rem)

What is it?

Unlike criminal forfeiture, civil forfeiture proceeds against the property, not the person. In theory, civil actions are remedial, not punitive like criminal proceedings. By acting civilly, the government seeks to remedy a harm, through the fiction of the property's "guilt."
...................
..........
.......

Once the government establishes probable cause that the property is subject to forfeiture, the owner must prove by "preponderance of the evidence" that it is not. http://www.law.cornell.edu/wex/forfeiture

Now, on a more positive note - :smile:

I'd really like to have something that'd fit between the obd port and my laptop's usb for realtime . Neighbors all have newer cars with check engine lights...i get a lot of questions.

Do you know of an easy to use gizmo for somebody like me who really dislikes abstruse menu screens?

Well, this is the one I use: http://www.scantool.net/obdlink-mx.html

I don't know if there's a good way to connect to a laptop, but it connects to a smartphone with bluetooth really easily. I use the Torque app (http://torque-bhp.com/) to talk to it, and it works great. Very easy to use, and no difficult-to-navigate menus. It'll read and clear codes, as well as give you any and all real time sensor data that your car has. That same company makes a version of the scanner that uses wifi instead of bluetooth - that one might work with a laptop as well...
