After Market HUD's & Lane Departure Warnings

When I was shopping around for a new car, I saw that Lexus and other similar class cars have Lane Departure Warning systems and a heads up display where the speed shows on the windshield. I am curious if there are any good after market systems that one can purchase?

There area a lot of sensors involved - I am not sure I would want an after market one but I imagine the cost to be fairly high. It is not a self start or alarm kit.

EDIT:

There also seem to be smart phone apps as well - though I would probably trust those even less.

Also - without auto braking the systems *may* do more harm than good:

Personally - I think the systems do 2 things.

1) Lead to over-reaction by the driver when warnings go off and
2) A high incidence of utter reliance on the sensors to the expense of paying attention and looking ahead and around....

I drove a T&C 3 years ago to Yellowstone from Ohio. It had the side warnings int he rear mirrors. I did not notice them till I really concentrated on them. I look over my shoulder and then glance in the mirror 2 times. I don't have enough time to concentrate on the mirror to see the lights - I am too busy driving. Even if I had a HUD I would still look - nothing, nothing beats looking imho.

The issue with the sensors is the same as the back up cameras - most people use them exclusively to back up - even if there is not enough of a field of vision to the sides. I have a van with a camera, the van we drove to Yellowstone had a camera, my ILs and father have even newer, more expensive cars with cameras and none provide enough of a fisheye to see to see to the sides nearly enough. It does do a good job of looking right back, especially at night when it is hard to see (heck at times I wish my car had a camera for dark nights/mornings) but relying on them 100% like a lot of people do - is scary.

Your eyes work pretty well as a lane departure system, as long as they are not looking down at a phone like most people on the road today. You're not going to find any reputable and trustworthy systems in the aftermarket. They are far too costly to install into a vehicle that wasn't designed for it.

I think some people want backup cameras to be required.

In general I think all these new sensor systems are the lead in to automated cars. Get the vehicle positioning sensors down in price and everywhere and gradually work towards a final system bit by bit. After all like all luxury systems they will eventually be in the cheapest Kia... Consider only 10 years ago even power windows were still an option on many cars and today I have only see things like fleet vans that still use cranks as far as brand new goes.

Yes - they do - to avoid running over kids/things right behind the car.

The problem with all these sensors and cameras is that people start to trust them too much and don't bother to actually drive their cars as much. An example of what I mean are the blind spot indicators that come on some cars. Chrysler uses a light in the side mirror to tell the driver there is someone in their blind spot. I've noticed some people with them don't even turn their head and check anymore. They fully trust the indicator to tell them. But what happens when that little LED indicator light stops working for some reason? And as a motorcyclist, I'm still not fully convinced the sensors will see me on my small bikes (though I do not linger in blind spots anyway).

I trust my mirrors more than the beepy thing my car does for reverse proximity sensing. Sometimes I wish the backup beeping based on proximity was actually on the outside because I find in parking lots people just the to walk and stand behind cars while also never controlling their kids. When I drove a pickup I had a two mirror policy for kids too short to see over the bed if they walked behind and did not exit on the mirrors I just assumed they were still behind and would give a short horn blow.

I just installed some ultrasonic reverse sensors yesterday and next month I might get around to installing my rear view camera, I figure since my radio has the option just use it.. plus I will be tinting the windows soon, but yeah people love to just walk behind cars but I have seen people just backup not looking at all.

I don't think this stuff is foolproof or a replacement for actually checking your mirrors and blind spots but I'm not against technology and things that may help

For example - there have been a few occasions where I had to pop into another lane because of stupidity ahead of me on the highway. I knew there wasn't a car there because I'm frequently checking mirrors and "counting cars" but a small icon in my direct line of sight would be a bonus.

I had use of an ML for a month or two that had lane departure correction, blind spot warnings, radar cruise, sensors, cameras and tiredness detection. The lane departure correction was frankly annoying. It could be set to passive or active where active would brake half the wheels to "pull" you back in lane. It would trigger on winding narrow roads, and trigger in unusual conditions such as roadworks where you had to cross lane markings. Since I don't drive while nodding off, 9 times out of 10 the lane departure alerts where therefore either incorrect or slightly dangerous. For example if it thought I was drifting into the breakdown lane but I was doing it for good reason, it would make a mild attempt to pull the car back which you had to resist.

If I had to pick from a list, I'd pay for blind sport warnings in the mirrors because they worked pretty well, and radar cruise makes freeways in thick traffic more relaxing. However this whole brainless co-pilot thing isn't working out so well.

I've always wondered... what happens when the lane markings are severely worn, dirt-covered, snow-covered, or even non-existent?

Seems to me like the lane guidance system would be very unreliable, annoying, and just another complex system to fail and require costly repairs in the future.
