I'd go the other direction. Make it JUST a watch and fitness tracker, no radio. Use a custom low-power chip to track steps and grab a pulse rate once ever 60 seconds; have the entire thing be powered by a replaceable watch battery. Garmin VivoFIT comes pretty close to this ideal.
Hyperloop is too narrow to transport existing vehicles. "Loop" may do this, but "Loop" is basically underground personal rapid transit -- subway with trains one car long aka a people mover.
Self-driving vehicles won't operate "practically touching each other" or move immediately when a light turns green. Slight differences in braking distances between vehicles would make this impractical, plus system designs would have to account for pedestrians.
New Federal standards allow basically unmodified European trains in the US -- lighter construction, more emphasis on crash avoidance vs crash safety. Caltrain is one of the first US railroads to be under contract to buy basically stock aluminium Stadler KISS train sets, the same equipment as Swiss Federal Railways uses on large parts of their network. Compared to overweight trains built to the dumb, old US standards, this hardware is amazing.
Here's what's missing -- on the East Coast, you can go from NYC to Boston, DC, Springfield, MA, Harrisburg, Poughkeepsie, Philly, Eastern LI, many parts of NJ, all via frequent commuter or commuter-type rail service. California can't even get LA-SF rail built. There's one train a day that runs via Oakland, doesn't even pass through SF directly.
Same dealio as "guns are freedom", while police shootings are 10x as frequent as in other developed countries and privacy protections are a hot mess. The US concentrates too much on SYMBOLS of freedom (cars, guns) not ACTUAL freedom.
MTA isn't controlled by the NYC mayor, unfortunately. It's a huge bureaucracy run by mouthbreathing hayseeds in Albany. Subways would run better if the actual subway system (vs Metro North and LIRR) were severed from state control and run by NYC directly.
You can get around NYC on foot, by bus, or by subway. LA is so sprawled that even 100 more miles of subway won't actually cover much ground. The subway hasn't expanded much, but the area's transit coverage has actually increased since the late 80s. NJ Transit built the Hudson-Bergen Light Rail, Montclair connection (enabling weekend service on the Montclair line), and Midtown connection (connecting Hoboken trains to Penn Station). Airtrains to JFK and EWR were built in the past 25 years. PATH is being expanded to EWR.
The issue isn't as much regulation (which allows nuclear power) as anti-science, ignorant, anti-nuclear NIMBYs. Basically anti-vaxxers protesting against a form of energy they know nothing about.
Better to do research in China than not do it at all -- the US is too mired in NIMBY'ism for civilian nuclear power research to be practical here. The goal isn't for him (or the US) to get rich, it's to increase the worldwide adoption of carbon-free nuclear power. He's acting as a philanthropist here and this should be respected.
If the train slows down even by 25%, kinetic energy is approximately halved. Also, slowing down even a bit might give whatever is on the tracks more time to move out of the way.
Nit to pick: "Conductor" is the person opening the doors and taking tickets, or "managing" a freight train. "Driver", "engineer", or "motorman" is the person actually driving the thing.
As far as automation, it doesn't hurt to have a set of eyes out front if there's a person on the tracks or a car about to get stuck in a level crossing.
Press F to send an FU to all of the obsolete coalies who'll no longer have a part in fouling the air with CO2. Glad the EU is doing the right thing and not subsidizing environmental depredation.
Cowardly idiots want a wall. Of course, you might be on to something -- the American public is full of cowardly idiots who have accepted bullshit like "papers please" when flying, increasingly intrusive security at public venues, idiotically harsh laws, etc.
Clearly, this is FUCKing awesome, we'll be able to see TITS on TV like every other civilized country. Even our CUNT of a President is sometimes right, even if this PISSes off a lot of Puritanical COCKSUCKing MOTHERFUCKERS. Hope they SHIT their pants at the prospect.
The problem is with "opt-in" is that it tends to spread like a disease. First it was airports, now it's stadiums, tomorrow it will be supermarkets, train stations, and shopping malls (as is already the case in pestholes like Israel). How long before we can't live life normally without some mouthbreathing security guard pawing through our personal stuff and violating our privacy several times a day?
As far as the Soviet Union, it wasn't our fucking problem, and it likely would have broken up anyway plus or minus a few years. Regarding Afghanistan, WE created the problem with the religious fundies by helping them against the Soviets. Afghanistan would have NOT fallen under fundie control if we had let the Russians take it over.
China? Let them take over Asia, let them have Africa. Not worth our money to stop them. The Americas can stand on their own just fine under the Monroe Doctrine. As far as installing QQ, that's no big deal -- just keep whatever Chinese crap is needed isolated on a separate device or virtual machine...

They can't continuously monitor pulse rate and pulse oximetry. As far as step tracking, step trackers have existed for ages -- mechanical pedometers.

Unless the US insurafilth mandate them for "discounts" on health insurance (read: not being penalized $200+ per month).
Do the wall warts powering smart spy-speakers even put out enough power to set anything on fire?
Everything you say is correct except the 3% grade -- Duffy's Hill is 12.6% grade, if only for a few hundred feet.
https://en.wikipedia.org/wiki/...
Fort George Hill is also 12-13%...
None of these hills are like the mountains in LA, but still not 3%.
BART =/= Caltrain.

Police help poor citizens? What dream world do you live in?
So exactly like every other form of infrastructure that not everyone uses equally. Deal with it -- it's part of the cost of a modern civilization.

The French have nuclear power down pat -- cheap, reliable, efficient.
They're NOT picking winners and losers any more. They're just letting the unprofitable coal mines go away.

Yes. I think the hysteria is overblown -- I don't think that schools should be turned into secure fortresses because of a few incidents.
