    With no LKA on my recently purchased (two days ago) 2012 v Five, I am in search for an aftermarket LKA. I had it on my 2010 and miss the added security. Does anyone have knowledge of a Lane Departure Warning system that can be added. I was informed it is possible, Toyota told me for $1395 (beeping) or $1595 (shaking steering wheel in addition to beep) it can be done. But I do not want to trust them with any more money. My Google search has not found a model yet. I will try to nail Toyota down as to what particular device they are suggesting they install. But I would rather invite comments here first. Thank you.

    In the other thread, a couple of people suggested that you ask them what it would take to GET a new car with that feature.
    Have you done that yet ?
    If not, you should. Really. Honestly.

    Believe it or not, if they charge you anything at all, it likely will be less that adding that feature on, maybe MUCH less.

    Do try and be practical here, please.

    The Mini 0803-0805-0806 Dash Cams have the lane keeping feature. They are very small and mount in front of your rear view mirror. The wire can be run quite easily hidden down the right side and back to the cig lighter plug. You have the bonus of a superb cam showing all your travels. Get the GPS version. Mine cost me $89 and does an excellent job. I mounted mine with the 3M velcro strips so it is easy to remove and replace. It turns on and off automatically when you turn on and off the start button.

    Could you give us a more detailed review of how well this works?

    While I am more interested in the dashcam features, OP would probably like to hear about the lane keeping feature (LDWS - lane departure warning system?) and comments about the conditions where it does and does not work.

    The Prius LKA includes some minor control over the power steering, as well as audible and visual warnings. But I suspect this DashCam-LDWS provides only a warning, with no steering assist.

    The lane keeping on the mini cam does only give a sound warning. I have only used it once to ck it out and of course it does sound off even if your turn signal is on for it is only a camera looking for the lines on the road. I have the advance tech pac on the Prius so do not need that feature of the cam. Will never buy another car without the adv tech pac. Bought the cam for incident purposes. Haven't had an accident since 1973 but nice to record all that is going on. I have the mini cam 0803 that is doing a good job but the 0806 is new with much changes and I will be buying it after it has been out a couple months. A search will bring up lots of info including videos.

    sounds like the near perfect solution.

    You'll have to remember that LKA and LDWS are two different systems!! Lane Keep Assist uses the electric motor in the steering wheel to nudge you back into your lane (above 50mph) or provide increased steering resistance in the "wrong" direction, while decreasing resistance in the direction of the centre of the lane, along with an audible warning below 50mph.

    Lane Departure Warning Systems only sound an alarm and are considered passive safety systems.

    I should be getting the Mobileye installed next month; and a break-in alarm on Monday. I will be looking for bling soon, like tinted windows, since I am apparently investing in this wagon. I do wonder what these nipples are for in the front corner fenders of the car, having not found them on any other, nor referenced in the manual. Shall I put tassles on them, radar detectors, black gems, some feature that is useful? They look like a design short cut. I had to put the photo in the Avatar since there was a 'problem' uploading.

    Proximity sensors (ultrasound) for the parking assist system.

    Interesting, and they laughed at me for wanting LKA. But then I had Driver Ed. in high school, back then, and know how to park. [​IMG]
    Got any ideas for the dummy button? Are there any features that could go here?

    And here's another Dummy Button I'd like to use or lose:[​IMG]

    Looks like Kokopelli on the instrument panel light control dial. That's nice.

    Tell us, please, how much those things are going to cost to install.
    (I will try my best NOT to say (again) that you should just trade cars.) ;)

    LDW on Toyota is an active system, not passive. It also nudges you away from the lane divider like LKA. The difference is LKA corrects the steering angle once the car gets back to the center of the lane where as LDW won't. In LDW, once it nudge you away from the lane divider, it continues on until tires ride on the opposite lane divider. It then nudge you back again. It keeps doing this until you correct the car to the center of the lane or until it cancels out. LKA is more aggressive in keeping you in the center of the lane than LDW. LDW is easier to drive with than LKA. In LKA mode, there's always constant steering wheel adjustment from the LKA steering motor. In LDW mode, there's no steering wheel adjustment at all until you're on the lane divider. It's only then that the LKA steering motor kick on to nudge you away from the lane divider. Also in LKA mode, if the camera lost track of the lanes, it double beeps. It's very annoying. In LDW mode, there's no beep when the camera lost track of lanes. The only notification is the lines on the dash display changes from thick to thin and vice versa.

    Thanks cpro! Didn't know Toyota's LDW was more advanced than the other LDW systems (which are passive).

    We don't get LKA here in Canada so I was just going off LDW systems in general.

    That article is ilrevelant to the Prius's LKA system. It talks about passive lane keep assist. The Prius has an active system.

    The study made by HLDI is well reported by other auto news outlet

    just to name a few.
    The original article can be found here

    Crash avoidance features cut insurance claims

    The article you've provided seems to report what the author had scan through the original article. He failed to report that the failed LDW were from Buick and MB and the most importantly the collision increases were not statistically significant.
    In the original article
    The study is based on a system that only warns the driver of lane departure. The Prius's LKA/LDW actively steer you away from the lane divider to the center of the lane. It's far more advanced than the car used in the study. It's the system that the article stated that they DID NOT test.

    Here's a more updated study on a Honda system

    Beware systems that lure you into a false sense of security. Even if they have a 99.9% chance of success, there is that one that will bite you because you thought the system took care of that and didn't look.

    I'll take my chances. In the 4.5 years that I own my Prius with LKA and LDW, it has warned me about 30 times on the freeway that I've drifted out of lane, give or take 10. According to your logic, I still have 960 times before I'll have a false sense of security failure. I'm looking forward to that 1 failure in about 112 years.

    Of course 99.9% reliability doesn't tell you when the .1% failures will occur.

    I'm not a perfect driver but at least, when I screw up, I don't have some system to blame.
