Title: Self Driving Cars, Self Breaking Systems
Post by: Traveler on May 21, 2016, 07:52:11 AM
Does anybody out there know anything about these laser and radar units used in the selfdriving autos?
I've seen several stories and have yet to see one address the question about all these new cars, here in the US, EU and Asia has been ahead of the US in Auto breaking and auto driving systems on the road for about 10 years now. My question is this, the Lidar and Radar systems used. What is the long term health issue, if any, of sitting in traffic jam with the guy behind you just inches away blasting your automobile and you and your kids with a continues stream of high intensity radar beam. Lidar is the Laser beam projected forward and to the sides to recognize the roadway in front of you, as well as the panic breaking system. Since any amount of laser light beam in the eye is to much and harmful, once these systems are loaded up and running in every automobile on every road, this can't be good. As far as I know there is no shielding on any of these cars, so that emitter in your side view mirror is radiating in all directions. From my airline days I remember having to shut down the weather radar so we didn't cook the guy holding up the red wands when pulling into the gate.

You don't have to worry about that guy long. First time it slams on the brakes and a 18 wheeler takes him out because he could not maneuver out of the way..... all will be good.
I saw a test of a euro car's self breaking system.... ran over several photographers. LOL

At lexus, we had a guy try to sue because it didn't automatically stop at a toll booth.

It's my opinion that a lot of people do everything but drive when they should be driving. Self stopping cars just gives them a reason to do more than drive when they should be driving.
Self driving cars will be overly expensive. If you are in one and the car has an accident, it will be the auto makers fault. They have to cover that expense when they sell the vehicle. The only way out for them is to find someone dumb enough to say "I trust your employees ability 100%". That would have to cover the computer and sensor manufacturer too.

I had a "Self-Breaking" car years ago. A 1973 VW Super Beetle. It was broken all the time.

A car that breaks itself? Why would anybody buy that?

Tesla's autopilot is frickin' awesome, i've got a 30 minute commute and it drives me the whole way everyday.

Some people are not drivers and are probably better off letting anything else drive.
I love to drive and would never waste money on something not needed.
Yes but when it's determined that driver less cars and trucks are fare safer then human controlled automobiles the government will just mandate that only automated traffic can use the federal highway system. It probably won't happen within the next 10 years, but perhaps the next 20.

So a 5ft piece of aluminum foil tied to fishing line would cause the radar to reflect, effectively shutting down the interstate?

I don't think so, I know that some of the software behind these systems are very sophisticated. What I don't know is that radio wave emitter in your side view mirrors to protect your bind spot is radiating at a constant and is not shielded , it's not a directional beam, it's radiating in a 360 degree arch and the drivers head is 6 to 10 inches from the left mirror, a few feet from the right mirror and that's just the radar, the lidar is a laser beam projected out the front of all the cars and trucks to recognize the roadway ahead and each side of the road, it's projected in a 180 degree arch. it's a laser beam of light that is projected from all the on coming traffic and all the traffic behind you, that laser light is reflecting off of all the mirrored surface. So when you adjust your rear view and side view mirrors, you will directing all the laser light emitted from the traffic behind into your eyes. No amount of laser light projected into the human eye is a good thing.

If it's LIDAR based it is very susceptible to interference. Low sun on a wet road can freak it out, as can bright LED lights. LIDAR jammers use a set of bright LEDs on the IR frequency to block police LIDAR.
IMHO self driving cars are a load of cobblers. They are ok for very canned environments but take them off well formed/well marked/well controlled roads and they quickly become scrap metal.

Makes you think of the taxi in the movie Total Recall.
Almost....I get distracted by the 3 breasted woman....but taxi is a close second.....u,,, Sharon Stone.....ummm can I think about it for a while...maybe 2 weeks :p

Tax money for the highway system will drop if people can't use them.

You will still pay the tax included in the purchase of fuel, if you mean tolls collected, I believe that the largest cost of our highway system is the human toll collector and his retirement and medical care. I've read an estimate that in New Jersey we will still be paying for the Toll Collector long after the last one has retired.

Texas doles it's toll roads, which are still very much frowned on here, out to sub-contractors.
Toll roads are a huge rip-off. Use our tax money to build them then charge us to drive on them.

My wife has been "self" driving my truck for years. Right from the passenger seat.

My mom used to have an official looking document named "Backseat Driver's License" but I suppose it expired the same time as her front seat version, due to old age.

I drive an 18 wheeler long haul (48 states). They have been placing these forward looking radars in the trucks for years, and they suck. The darn thing will lock onto bridge overpasses, signs and such and slam on the brakes. Never once has the system helped me. Imo, it is absolutely dangerous, esp in snow and ice. The only thing that I do like about it is if my truck is governed just a hair faster than the one in front of me, it will lock on and match that speed with a following distance I am comfortable with. It's better than taking 10 miles to pass the other truck.
I need stuff that helps me stay safe. I like the side scan radar that alerts me when someone is in my blind spot.
I do not need help driving the semi or keeping it in the center of the lane. All these bells and whistles are a major distraction and drive you nuts. The last radar I had would actually blind you at night, so I had to keep cardboard taped over the display.
It's a bunch of stupid crap the REAL pros DO NOT NEED!! However, the companies get a nice insurance break by equipping the trucks with this junk.
