A fuel pump is a machine. Machines have been developed to do battery swaps too. If there were the incentive to do so, it would be technically feasible.

Think you'll find this car won't reach those speeds on 99% of its routes either.
This car probably is as well. - Just one has a really long extension cord, and the other one fills up batteries and carries them around.
By using an electric drive system to capture the energy, rather than dumping it in a brake?
The article says they asked 2000 children, but there's no mention of what bias may have affected the sample of children that they asked. They may have mainly asked older children in that range, which would have skewed the results greatly, compared to evenly sampling across the age range.
The "as young as four" remark demonstrates that there were no 0, 1, 2 or 3 year-olds who owned their own phones, which would account for 800 out of 2000 evenly sampled children. That means among the 1200 4 year olds and up there must be 667 with phones, ie. 56%. Further assuming the proportion increases with age, at 9 years old it would be much higher than that.
Solar power to run the lighting inside? How about just using the light directly via skylights?
What if you can point your smatphone at the t-shirt you like, and it identifies an online merchant selling it direct out of China for 1/10th the price, shipped to your home? No worries haggling with French salespeople, no having to carry it around for the rest of the day, and no bloated luggage. Maybe with a licensing deal, the brick and mortar store could even get a cut out of it, and not have to worry so much about inventory.
Is there "good" and "bad" mileage? If it's about road wear, then pavement damage goes with something like the cube or more of weight, so the truck is likely to do more road damage per litre of fuel used than little Johnny's car. If it's about traffic congestion, trucks also slow traffic flow. If it's about CO2 emissions, then emitting 1kg of CO2 from the car taking Johnny to school worse than causing 1kg of CO2 to be emitted from getting stuff delivered?
Chelyabinsk also has a reputation as being the most contaminated city, with nuclear contamination from Mayak. Now maybe there's a connection..
Many car speedometers do use digital readouts. The issues against them generally have more to do with readability in bright sunlight.
In terms of display, it depends on what information you want to extract. In the case of a car, is it the approximate speed - ie around 80km/h or around 60km/h?, or specifically 2km above or below the speed limit? The human brain will generally process the first of these faster with an analogue dial, but the second may favour digital. I find it a lot easier to get close regulation to a speed limit with a digital readout speedometer than a conventional single dial analogue meter. If you just want an approximate speed: take a look out the window and you can feel that.
Where digital fails is when there are many values to process of varying scales - such as engine temperatures/pressures/levels etc, or where the value can change quite rapidly, such as a tachometer. Digital speedometers still have value, just because we tend to drive against nominated speed limits all the time, and are just dealing with the last digit.
Problem with shortscreen monitors in portrait mode is they end up too narrow. I use a pair of 1024x1280 tallscreen monitors in portrait mode. The vertical is just about right, but they end up a bit narrow on contiguous space for some applications. A shortscreen would only be worse on that.
Similarly, you don't lose anything in going from 1366x768 to 1366x1024. It's just a tall widescreen then.
Exactly. Is this discussion US-centric in not mentioning SIP??? Here in Australia SIP seems very common right through to consumer use of VoIP, albeit mainly for calls to the PSTN. A lot of modems even include a SIP client and hardware for an analogue phone adapter. People generally don't seem to have trouble getting it to work behind NAT. I've had troubles in the past with Ekiga, but Twinkle has worked reliably for me to connect to my SIP provider.
Regardless of where you buy most of your parts, car companies still make a lot of money in the sale of "genuine" parts.
It's probably more likely various odd 12-point drives, or a specialty 33-spline bit referred to... not standard metric tools. They are available, but for the cost of acquiring the tools, makes it more worthwhile to get the job done at an authorised dealer for the average owner.
