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.

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.
