Why do we never see these cars being tested in white out conditions or on icy hills? Don't they have their autonomous wreckers ready yet LOL!
(quoted from post at 15:11:27 01/17/18) A self driving car will know the train crossing is there and that a train is approaching miles before it ever gets to the crossing. Trains will send out a locator signal that the cars will read. Same with blind intersections and cross roads with stop signs. A self driving car approaching the intersection will know about every car close to that intersection, its speed and direction of travel.
(quoted from post at 15:42:20 01/17/18) Take away the inexperienced driver, yes they will do less dumb things.
But can it anticipate an icy bridge before it is on it?
Can it build speed to make an icy hill?
Can it decide "this ain't worth it" and go back home? LOL
(quoted from post at 15:47:17 01/17/18) lets get back to Eldon's original post, I'm sure in California and Arizona where the weather is nice this concept can be made to work fine, up here in Canada where you can go through freezing rain (LIKE WE HAD EARLY THIS MORNING) or drive into or out of a blizzard all within 3 miles. or when you walk out to your vehicale and it's covered in an inch of frost and ice, and all the lane markers are covered in snow or ice?? how will the computer systems function in high humidity/severe cold conditions? the new trucks, equipment, cars and trucks we are getting up here aren't doing so well. a locale oilfield hauling co. my brother inlaw works for had bought 5 brand new 2016 peterbuilt tridrive winch tractors and after getting all the rigging and decals and paint done they where sent out to a rig move about 300 miles north. one made it about 30 niles from the yard, two made it to grassland about 80 niles ne. one shutdown at wandering river, about 200 miles and one made it to the rig! at $500,000. each the owner was not amused.
(quoted from post at 16:03:59 01/17/18) If someone steps in front of my car I stop now and wait for them to move. So how is a car doing it automatically any different?
(quoted from post at 19:07:59 01/17/18) The biggest challenge I see in autonomous vehicles isn't a technology hurdle but rather an
ethical one. Whenever we get behind the wheel we're assuming an enormous responsibility to
others around us and are also assuming a risk that other's actions may injure or even kill us.
Events arise on the road without warning that can never be planned for and it can require a
split-second decision to determine the "lesser of evils". For example, do I run over the kid who
just jumped out in front of me, swerve left into oncoming traffic, or swerve right and crash into
a tree? The human driver makes a decision and acts on it based on what just feels right at that
moment and provided the action was taken in good faith nobody can really fault the driver
regardless of the outcome - he was put in a situation that had no good options. On the other
hand, an autonomous vehicle would need to be pre-programmed for such an event. In this case
regardless of the outcome the vehicle manufacturer will probably get sued by either: A) the
parents of the kid because the car didn't swerve and ran him down, B) the family of the driver of
the oncoming vehicle that was killed when the car swerved into him, or C) the family of the
autonomous vehicle driver who died crashing into a tree. To program the vehicle controls for
such an event would require a company deciding what the "lesser of evils" is and as such would be
picking the "loser". This has liability written all over it. And what if the detection system
only thought it was a kid when it was really a large dog? It would be hard to justify a loss of
human life to save a dog.
Yes, it's a hypothetical situation but this is the kind of thing that needs to be worked out
before autonomous vehicles become mainstream. Computers don't have the ability to think and
reason - they can only follow lines of code - and to be programmed to execute a "thoughtful"
response to every conceivable situation will be a massive undertaking.
(quoted from post at 15:35:23 01/17/18) It will have multiple navigation signals. GPS, radio with other cars, on board vision, on board thermal imaging and stuff I can't even think up yet. It won't depend on single sensor. Multiple sensors of different types with backups. It probably won't let you drive through a 4 foot snow drift and you shouldn't do it now. So being stopped before the snow drift but not stuck or in the snow drift and stuck. Not much different. How do you clean you windshield now? Wipers? Defrost? Same thing can be used to clean sensors.

(quoted from post at 08:25:52 01/18/18) This debate will go on just about forever.
My opinion of autonomous cars is that they are a stupid and dangerous idea. Then there are people that will try to do it just to see if it can be done.
I can't see AI ever becoming "smart" enough to make every decision correctly that might arise in just normal driving. Mixing human drivers with autonomous vehicles is a recipe for problems. Humans are unpredictable. Computers are only as smart as the programmers that program them.
Sooner or later, the government will get involved.
Personally, I think that they should be limited as to where and when they can travel, and should be segregated from the general motoring public.
