If I remember correctly, it's forbidden in Romania to use intermittent (red) lights (that is, if you're not the police).
I still use them on my bicycle... but they're illegal.
With one mention: the roundabout offers much better chances of going from the side road - even in that extreme case - than not having a roundabout (and no semaphores). I know, I've used to exit from a side road to a major road, and after the roundabout was set up, it was so much easier (you have to yield to only one direction of traffic, not to both)
"with far less wear and tear to your body and fatigue from the work than a regular person would receive"...
Body building is quite a drag on your body - it's especially very hard on the spine.
Road work. Construction work. Farm work. Even being a garbage man (on trucks without motorized loading) takes a bit of strength and stamina. Working in a tire changing shop. Ambulance men, medical assistants (the ones that carry the patients on stretchers). Policemen (when they need to immobilize uncooperative persons). Loggers (wood cutting industry).
Not to mention that the aircraft doesn't have to carry consumed fuel, while it has to carry consumed batteries. And in some cases, aircrafts take off with near empty fuel tanks but with overweight loads and refuel once airborne.
Assuming a slanted roof (oriented to south), you'd get at most 3500W from the device. In an 8-hour day, with some 60% total efficiency, you'd get some 17 kWh. That would be enough for the i3 I think.
This thing would be advantageous if it would keep the car in the shade during summer, and clear of snow in the winter. A garage would be better, though. And maybe setting the solar panels on the house is either too expensive, impossible,...
If the "toy guns" are perfectly able to shoot one effective bullet (even while disintegrating themselves after that), then I'm not considering them toy guns. By the way, I think a 3D plastic gun was able to shoot 8 bullets before being too damaged to function (a 3D plastic rifle fired 14 rounds)
And where would you draw the line between toy guns and "real" guns? 3D printed in plastic = toy. 3D printed in plastic with one metal part? With two metal parts? With multiple metal parts? Handmade on a lathe?
The Falcon 9 can launch with 8 out of 9 engines working. For this, I assume they pack some extra fuel. Maybe they won't be able to soft land with one engine broken and the extra fuel consumption, but if all goes well, there's some extra fuel that has no more uses right now, so they could burn it for a soft landing.
It's higher than residential speed limit, which is usually something like 30 mph or 50 km/h. My highest speed on a bicycle (downhill) was some 65 km/h (scary fast when cornering), compared to the 72 km/h of the elevators.
Most of the vaccines are safe, and most of them are effective. However, there are many vaccines with spectacularly bad side effects on a minority of people, and some even with side effects on every taker. I would put the exceptions mostly on technological problems or medical "conditions". And vaccines (in case of epidemics) protect both those that took them and those that didn't (considering that a large immune population reduces greatly the spreading of epidemics) - "I haven't took the vaccine, and I'm fine" is quite plausible if everyone _else_ took their vaccines.
Actually, "client" workloads (personal computers) aren't very parallel so the requests are served sequentially. As such, this won't help too much.
Even now, hard drive performance (if computed separately for client-workloads and server-workloads) uses queue length 1 for client and queue length 32 for server.
By the way, if I remember correctly multiple requests on flight were implemented on SATA standard for client drives, 10 years ago or so on (SCSI had them for quite a while). I'm not sure Windows XP uses these queues.
Seek time is the time for r/w head movement (closer or farther from the disk center) PLUS the wait time until the wanted data is rotated under the read/write head. So, unless you go with r/w heads for each sector on the hard drive, you can't reduce part of the seek time. And you could rotate the disks faster (like in SCSI 15k rpm disks), but there's a limit there too.
Will HDDs ever be performance-competitive at the same cost to SSDs? At the current technology level, no. Will SSDs ever be price-competitive at the same capacity? Hardly, considering adding another platter and r/w head to a hard drive is a quite inexpensive way to increase capacity, while adding another set of flash memory chips is an expensive way to increase capacity.
(oh, and a read/write head for each data strip was used in the 50s and 60s - see magnetic drum memory).
They must have extra fuel due to the "launch with only 8 out of 9 engines working" - when flying with 8 engines, they need more fuel to accelerate as they have lower impulse. Also, the engines' output might vary somewhat, so they most certainly have excess fuel. I'm not sure if all this excess fuel is enough for a successful landing or they might need more...
This electrical cable can function as a tether. Maybe a steel cored, twisted aluminium strands cable (as used in medium and voltage transmission) would offer both low electric resistance, high strength, high reliability,... (P.S. I have small lengths of that kind of cable at home. It's probably overkill for a 10-houses sized balloon, but it can be built in smaller gauges)
This can reduce waiting times in "taxi rush hour" - would you prefer to wait 15 minutes for "your own" taxi, or share one that comes in 5 minute? Also, if the cab carries two different passengers, cab drivers get payment from each.
In Athens, Greece, the cabs that carry one passenger might stop and take another one that goes in the same direction (and get full payment from one passenger and partial or full payment from the other). It helps a lot with the "I can't find a cab at this time" problem.

Delays don't matter much if the launch is a success.
If you have a contract with guaranteed time with a local, you keep that contract of pay early termination fees.
Romania has started Metrification about 150 years ago... but I'm still referring to mountain bike wheels as "of 26 by 1.9" (inches that is).

Teeths appear no earlier than 6 months, and usually at about one year of age.

You might try next time to use CloneZilla. I've used it to "copy" from and to partitions of different sizes.

Maybe because what you consider "almost universally derided by players everywhere" is just "the vocal minority"?
