Oh and before I forget... me and my colleagues are always coordinating... if we have to go further than say 5-10 km, we almost always fill our car.
4-5 people on a GPL car is way cheaper than train taking into account gas cost only; I don't know if it's also cheaper taking into account maintenance & taxes, or even the cost of the vehicle, but since as I already explained I have little choice in that matter, those would be there anyway.

If you're referring to AF296, that accident went down another way.
It was a low fly-by, not a touch-and-go, and the cause of the crash was either the lag in engine spool-up (i.e. pilot error) or the computer entering landing mode below 100ft AGL.
We have a final report, though it has been disputed by the captain of that flight, and there are some incoherences.

Public transportation is almost never viable for me.
I often have to go to places which are not served by public transportation - by that I mean nothing (train, bus etc.) gets in a 20km or more radius.
It happens that I get a job with a 2-3 hrs notice. No time to arrange for transportation other than my own car.
And finally, I often end my shift very late, 1-2hrs after the last train, and I still have 80 or so km to cover.
Those times I can go on foot, I do, even if it's a 2hrs round trip, but otherwise...

To drive is fun, in abstract.
You know, those beautiful, empty country roads you see in the commercials, with leaves rustling after the car silently passes.
Or those winding mountain roads like that famous one in Romania.

Then you start your very real car, and spend the next hour jammed in city traffic, with mopeds that try to get run over by you by passing you then swerving in front of your hood and braking hard in order not to hit the car in front, or trying to figure out the intentions of people scrambling at the very last moment for a right turn from two lanes on your left.
And when you finally get to said country road, it is really deserted as in the commercial save for the old man with the decrepit Fiat Panda, who drives at 30km/h, but whom you never manage to overtake, because in the straights he suddenly accelerates ("hey, it's easier here!"), and always drives in the middle of the road anyway...

Oh and lest we forget... the geniuses with SUV and sedans who only drive in the fast lane on motorways, going 160 km/h and signaling you to GTFO of they way with their headlights...

Autonomous ASAP for me.

Exactly.
I mean, a pitot tube is way more exposed than a radar dome (because of the cavity), and can be subject to really, really low temperatures.
The one that clogged on AF447 is said to have encountered super-cooled water droplets in the region of -40C (IIRC), but that particular model was known have a weakness, and its replacement had already been planned.
Where do we find snow or ice at -40C on earth? the poles? Siberia? so I'm quite optimistic at least regarding the temperature issue :)

Pitot tubes on aircrafts have anti-ice systems.
Increased complexity, I know, but... hey we are talking about a car that can drive on its own! :lol:

Heard of it, never tried, but I could :)



Yeah, but why another 200-300€ to spend, batteries to charge and devices to forget home - never mind the fact that map updates are probably not free after some time?

My phone is always with me, I put it in the holder at the beginning of the trip, if a call comes in I simply ignore it, pull over at the first opportunity and call back.

uh... in theory.
My car doens't have a GPS, and because of my job I'm often required to go to places I don't know, which can be pretty remote BTW.
Florence has been a single huge building site for years, because of the new tram system being built (3 lines completed so far), so things change constantly, and by that I mean one day from the next, not one month from the next.
While I wouldn't dream of texting or calling while driving, I appreciate the convenience of Google Maps enormously.

@photoptimist this was also a topic on the Mayday - Aircrash Investigation series.
Apparently man is a good "performer", but a bad "monitor".

@PDL 's objection was that GPS doesn't work in a whiteout.
Apart from that, I agree - also considering that by "GPS" we now refer to more than the GPS constellation proper (GLONASS, BeiDou, Galileo...)

I can't understand why you are picking on me... I'm never confrontational, and I merely expressed a personal point of view.

Regarding autonomous drive, I think there are far bigger issues, and far less infrequent than whiteout.


Regarding the wire question, I think that a paradigm change that big, if it ever comes to be, would justify an investment in infrastructures.
If there's the will and the advantage, it will be done, otherwise it won't, or other ways will be found to achieve the same result.

Regarding the implementation, I was thinking more of a "dumb" wire, that doesn't trasmit anything, something like a Hall effect sensor on the car, but there are other solutions that don't require the wire to be intact from start to end (e.g. RFID). Besides, some redundancy could be built-in.

"General weak statements" are often called "conversation", and I don't think one should be required to have a major in robotics or whatever to be allowed to express his point of view in the General Talk section of a Photography forum...

I agree with that.
Perhaps with some sort of infrastructure, like wires embedded in the concrete under the surface markings.

I'm not sure what you mean by "not telling the contents of your argument".
I pictured a scene similar to the one you described, and figured that if sensors on a car can get no visibility, the car will slow down or downright stop if programming is good enough.
I'm not saying it will happen "tomorrow" either, and I was talking in abstract, test-like conditions as well.

But I can program a car so that its speed is linked to visibility, grip, visibility of horizontal markings etc.
If the programming is very, very conservative, it the worst-case scenario it will simply stop moving.

I don't think driving on slippery surfaces should be a particular challenge for autonomous vehicles, after all both visibility (night & whiteout) and slipperiness (ice) are easily measurable quantities.
Only issue I see, is that the car has to be programmed to take those values into account... otherwise it can easily put itself in a situation it can't get out of, without knowing it, e.g. perfect acceleration in a straight line, on ice, thanks to the traction control up to say 50 m.p.h., then a sharp turn it was not prepared to encounter and straight into the ditch it goes...

Something wrong with the link, even removing the extra "http://" at the beginning.
Ah that's it, the colon was missing in the path, this should work better: article.

Reading that now, thanks for posting :)
