It all depends on lactase persistence and that depends on genetics. The relevant mutation in the gene for lactase is relatively new, without it you simply can't handle lactose after puberty. The mutation is common in people with Caucasian ancestry, in purely non-Caucasian ancestry lactose intolerance is extremely common. If 90% of your adult population gets the runs from lactose then cows milk isn't going to appear in the national cuisine, except for maybe as a drink for children. It is an interesting gene to trace because it isn't old enough to have spread over the globe yet.
A good manual saves 80% of helpdesk time. A really good manual saves 90%. Ikea manuals are really good. They even allow their products to be less logical in construction, resulting in lower production cost and lower transport cost on top of the lower helpdesk cost. The manual is a one time investment, the others are continuous. As with all things, this is a balance. Making a good manual costs time and money. I wouldn't be surprised if each IKEA product is assembled according to the manual a few dozen times before it lands in the warehouses, in addition to the time spend on writing, drawing and revising the manual. Ikea can recoup that cost as savings amortized over many many products, but not all products have such a large userbase that the invested time and money will be returned.
How do they actually work? Do they do any kind of entropy calculation, or check the data against known rainbow tables? Or do they just apply rules?
AFAIK all I have seen clearly use a set of rules. Seems to be: length + number(yes/no) + symbol(yes/no) + capital letters (yes/no) For each "yes" a value is added to the length. The resulting sum is the metric. Advantage is that it's easy and fast. Disadvantage is that it's not all that good. Dictionary check + entropy calculation (using a dictionary for "correct battery horse staple" type password entropy checks) would be better but would also require far more computing power and availability of a dictionary. The user doesn't have a suitable dictionary so you can't offload the calculation to the user.
Dunno how it is in the US, but here in the Netherlands you are obligated to prevent parts from dropping off your car. Also, the quite thorough yearly tests check for such cases. The first car would be liable. In practice it is impossible to find liability in such a case. If I drive behind a car that looks like it's going to loose parts I'll keep an appropriate distance. It doesn't happen all that often.
There are no permanent fixes in our world. Things wear and need maintenance. One inch a year should be taken into account with normal maintenance but that doesn't mean it'll cost extra.
Lithium batteries will be available to them in large quantities, assuming they take back the old batteries from their cars. Lithium batteries that are too old to be used in a car can be used in this way.
At sufficiently high temperatures most plastics don't produce toxic fumes. Only PVC and fluorcarbohydrates produce toxic fumes. However, I am talking about somewhere over 1000C. Not your average stove. Assuming a clean O2 source you'd have only CO2 and H2O in the exhaust. With air you'd also have various NO compounds, due to oxygen and nitrogen in a high temperature environment.
Wood doesn't produce creosote at these temperatures either. Only fall ash, fly ash, CO2 and H2O (and probably NO compounds). Fall ash and fly ash are components of modern gypsum and concrete.
GPS is neither reliable enough nor accurate enough to stay on the road. Google knows this, that is why there is a LIDAR on top of their cars. The times I have driven in heavy snow I had tracks that indicated where the road was. A self driving car will detect those tracks even more easily because humans rely on contrast while self driving cars will have LIDAR, SONAR and/or RADAR. When the track does not follow the road sensors in the suspension will indicate that there is something amiss and correct back on the road. The speed the car will have will allow it to correct safely.
Europe is mostly on 240V. We would only need 30A for it. Dunno if 100A is common, the house where I knew the main breaker value had 3x32A (three phase power, used to include an attached farm).
Separate circuits are usually 16A here. A 32A breaker would require new heavy duty wiring from the breaker box to the charger. Probably 4 mm2. And that is in addition to the potential thousand bucks to replace the main breakers and the additional fee because of those heavy breakers.

An hour of fitness a day is quite different from full day working on a field with only an ox instead of a tractor.
Inclination is 23 deg. This is sufficient for 100% sunlight in geostationary orbit.
Sugar is always far from fundamental.
Salt is only fundamental if you're in a hot climate. In most climates it's not fundamental.
We're also not doing as much physical labor as 40k years ago. Such a radically different behavior requires a different diet.

FruitLoops is fruit. It says so right there in the name.[/sarcasm]
Last IKEA cabinets I build had "L" and "R" printed in hidden places to solve a similar problem.

I wonder if it's feasible to capture the uranium from the fly and fall ash from coal plants, because those things put out a lot.
Download the stuff so you can host it on a server of you own.
So long as the browsers hide my password with dots copy pasting is the only sufficiently reliable way to get temporary passwords right.

That computer would stop on the on ramp of SF bay area highways and refuse to move.
Why? Too steep to brake? Too many tailgaters?

Flying cars are easy.
Water often looses. See the Netherlands. In fact: hire the Dutch to design your wall.
They do have yellowcake.

At the moment most battles aren't fought in space.
A major problem with worrying about both is that we need electricity.
Not even if you forget the time to make the pizza. My local Domino's gets the pizza to my place in half an hour and that is including making it.
