Apparently the primary vehicles on roads are trucks and essential goods (food) are flowing reasonably well within Italy, less so between countries. With most other vehicles off the road deliveries are being made in record time with lower stress and fuel costs. Fortunately Italy grows most of its own food. Time everyone went of a diet anyway :)Quote:

given the current travel restrictions on overseas students, if they're not currently in country they probably won't be able to enter at all this year.Quote:

I also struggle with the "herd immunity" concept. As far as I can tell the concept is based on allowing "just enough" people to die that the remainder build up a sort of herd immunity, which could be expected to suffice till there's an effective vaccine.Quote:

Assuming that the first vaccine is just good enough to reduce the death rate by 30%, a person might require 2 or perhaps 3 jabs as the vaccine's effectiveness improves to something akin to the current flu and pneumonia vaccine.
Perhaps, we need to think of the current pandemic as being akin to being in a war zone that covers the entire country.
At some stage everyone will be exposed to the virus. If the disease's progression can be slowed there's a very good chance of minimising total deaths.
But to slow the virus's progression, current suppression methods might need to be in-force till the end of the flu season in late October.
Not a pleasant prospect for a person currently in Canada.
at this time of the year, the lane and edge markings have been scrapped off Canadian roads by the snow clearing operations.Quote:

And you don't want to know the cost of upgrading the Hume to allow fully autonomous trucks to operate.
Here are some Regional Italian stats from a major Italian Newspaper.
Ricoverati con sintomi - recovered showing only symptoms (mild case)
Terapia Intensiva - undergoing/gone intensive therapy
Isolement dom - domestic isolation
Totale etc = total positive cases
Dimessi/Guariti = discharged from hospital recovered
Diceduti - deceased
Casi Total = total cases
Tamponi - total numbers tested

What you can see is (like China) that most of the cases and deaths are occurring in about 4 regions (with about the same population as Australia) the other regions have lower numbers because they are still behind the curve and are probably better protected because they went into lockdown before their numbers got too high.
The death rate as a percentage of cases in the main infected region ( Lombardia) is >10% probably because of lack of ventilators and staff.
In Veneto (mums rellies) where they have enough ventilators and staff the death rate is 2.7%
In Trento (Dads rellies) where they don't have any big cities, only a few large towns and lots of little isolated villages. They have excellent health facilities and the people are in some ways more germanic than italian so are less likely to cut corners, has a death rate of 1.8%
The comment was intended to be tongue in cheek while having a little bit of a dig at the whole idea of autonomous vehicles (at least for the foreseeable future) and AI in general.Quote:

To my mind, the road system is just too complex an environment to allow for automated vehicle operation.
And requiring a live person to "monitor" the operation of the autonomous vehicle is beyond a joke. NASA has done experiments that clearly demonstrate that even when highly trained people are required to "monitor" the operation of a vehicle they just can't. Their reaction time climbs into the 10s of seconds, if not minutes, primarily because their attention wonders onto other things. Even a thing as seemingly innocuous as cruise control leads to a person's attention span blowing out.

In the OTHER thread, on climate change (that thread was the biggest until this), is that auto-cars and auto-trucks would be an excellent advantage to have now.
I can almost guarantee that the trucking companies are ramping up their automation efforts.
I'm reminded of a book I read a looooong time ago, by Bill Bryson, in which he discussed as part of his style of rambling narrative, about how the plague locked Isaac Newton indoors for quite a period. In this period he had time to reflect (haha) on many of the attribute of existence and supposedly came up with calculus, the anatomy of light and a few other interesting things.
So good can come of bad. Ill see if I can find that. There is reference to it here: Isaac Newton - Wikipedia
Hi Ian, You may want to qualify that belief system. Fully autonomous vehicles have already been utilised within the mining, farming, construction and warehouse sectors and shown drastic improvements in the productivity, worker safety and economy of these industries. Mining in particular continues to make multi-billion dollar investments in this tech. And if you get the chance, get a tour of some modern logistics operations. No forklift drivers or yard vehicle drivers in sight.Quote:

Just a qualification of this (and without wanting to hijack this thread) just thought it worth mentioning the BHP autonomous train that had to be deliberately derailed almost exactly a year ago in the Pilbara after having travelled 91km without a driver. At a cost of $55m per day till the track was repaired one can only speculate how far that set autonomous trains back in their development...and that was only going from point A to point B!Quote:

I got a reply from my friend, the specialist in public health, sent at 3.30 am this morning - "... so much going on that I can't sleep so I may as well answer your email..." and then essentially gave me a lecture. Summarising:
You should never refer to the rogue virus as coronavirus; it is COVID-19.
Coronavirus is a massive family of closely and not so closely related viruses that are constantly mutating.
By analogy with the animal kingdom: lions and tigers are both members of the cat family, neither are dogs, and there are several sub-species of tigers. All can interbreed including lions with tigers and other large cats but commonly do not because of geographical or preference factors. Corona viruses are less well studied than cats, and probably more complex. The constant mutations are a real challenge to researchers and pose the limitting factor with flu vaccines and treatments.
COVID-19 is a type of coronavirus.
SARS is a type of coronavirus.
MERS is a type of coronavirus.
Influenza is a series of types of coronavirus.
So simple, so complex.
An absurd situation at ALDI this morning. They have decided to open at 9.30 instead of 8.30 to allow staff extra time to stock the shelves. Last night they sent out an email to those who have set previous "product availability" reminders. (also advising that you could no longer return bumroll because you were an idiot and purchased 100 packets).
At the time of reading the email I thought "good idea, and fair enough" because retail staff would have been copping heaps in the last weeks.
So this morning I showed up at 9.30 because I wanted to panic buy a $100 coffee grinder (which is pretty good BTW). There were two queues outside the two ways in to the store (which meet at the main entrance, and there would have been about 200 people - which will soon be illegal...).
The main point here is that NONE of these people were practising social distancing, and were all within 30-50cm of the next person ahead of them. I was the only person to stand on the other side of the 1.5m wide ramp (3 ramps each at least 20m long). That gave me a triangular distance of about 1-1.2m from the people before and after me. Those people respected my wishes as the queue slowly inserted itself into the store at 9.30.
But what about the people at the head of the queue? They must have been there for at least 20 minutes I'd say...with dickheads right on top of them. :doh:
I quickly grabbed the grinder and headed for the checkout. The woman behind me wasn't just close....she was brushing against me in her rush to place 4 small items on the rolling counter (I was just holding the grinder box to avoid contact with anything). I turned around and gestured for her to keep back a bit (just held my hands up slightly) and she objected! Decided she should feign a cough for my benefit. I said "That's why" and apparently it was only because I was "carrying on" (by a slight gesture with my hands). W.T.F. is the matter with people? :(( I said to this idiot "I am only trying to do what the health authorities have told us to do".
The manager was standing there on my way out so I said that whilst I understood their need for more hours to restock, the queue that was the result was a disaster, and that the needed security guards to keep people apart in the queue. He said "We've got one there." Yes, standing at the door doing NOTHING. They need one on each ramp for about 20-30 minutes before opening, or at least a staff member (probably sufficient) to ensure people stay apart.
I'd be pretty sure the whole opening an hour later at 9.30 has only increased the panic. It must be bedlam in the big(ger) smoke.
And IIRC it was a human error in the first place that let the train go out of control....Quote:
