I don't think it's fair to insult all US citizens because of your personal shortcomings.
Do you not have personal experience with people under 40 in America? I would bet $20 over 95% of them don't know how to balance a check book.
I think electric motors should focus on other vectors.

But why limit only to cars? Can this be used for motorcycles, e-bikes, electric buses, train wheels, e-unicycles, electric golf carts, etc? There are probably a range of application where in-wheel makes perfect sense.
Motorcycles I could imagine. Do e-bikes really need significantly more power than they have? They already run arguably dangerously fast for their application. Is efficiency not the primary target there?
I'm always interested to hear about the latest in lighter and possibly more powerful and torque-y e-bike motors.

Much better you should post it and somebody mark the banner ridden one for deletion.
'Supercarblondie' manages to hit everything I dislike about automotive marketing online all at once.

That seems unlikely, a proper Brit would know that a stone is defined for body weight (14 avoirdupois pounds), Wool (14, 15, or 24 pounds depending on wool class), Wax (12 pounds), Sugar and spice (8 pounds), or for Beef and mutton (8 pounds). ( Of course Scottish Britains used 16 Scottish pounds for a Scottish stone ). The point being that 'precious' metals used a different weight measure altogether .. (common lead…
Prior to the Revolution, in France alone there were allegedly 250 thousand various units in use! (All sorts of units, not just length.) It didn't help that pre-Revolutionary France was a political Frankenstein stitched together from dozens of regions with completely different history (Celtic Brittany, Flemish Dunkirk, Germanic Alsace, Provencal South, Catalan Roussillon, Italian Nice) and thus very different local st…

Mid-air: yes. A boom with a charging cable or even beamed energy would be much easier. On the ground: swapping batteries is faster, and batteries are cheaper than planes or drones. You want the expensive part back in the air as soon as possible so you don't need as many of them. On the whole this probably also simplifies logistics: in civilian aviation airport space is limited, in wartime it's easier to transport one…
That's a future thought when it comes to electric aircraft - remote/emergency refuelling. I know they have tested lasers, and even sent a megawatt in 30 seconds over a distance of a few miles, though current convention of the laser back into usable power is around 50% efficiency. All gets down to a needed leap in electricity production and wished the World would get together on fusion reactors and knock it out the pa…
A laser over 10W has safety implications. This is 50,000 lasers all shining on the same plane.
Given your collectors are only going to be say 50% efficient, you're likely going to dumping enough wasted energy into the wings to melt the aircraft - not sure what dumping 3MW of heat energy into a plane would do over an hour, but I suspect it would stat to melt in a few seconds if you're lucky (otherwise your passengers would start getting very toasty)
At 3MW for an hour that's not a great amount of electricity that's needed - at 10c/kWh it's $300 an hour. You don't need fancy things like fusion to generate that. In the UK alone Solar is currently (in November) generating 600 times that - plus domestic installations.

No wonder electrics don't sell well in the US. People weigh more, you're basically saying that leaving grandma at home, is a "game changer".
Range being worse with a fully loaded car than with a lightly loaded car isn't exactly news, and not exactly limited to electric cars. I can clearly feel my old diesel struggling more when I'm driving 3 friends and with loads of heavy stuff in the back than when I'm alone. That makes the gas bill more expensive.
In an ICE, the same load is less visible because most energy gets wasted as heat. This is also why cold weather seems to affect EV range more.
Feels like a vanity metric, electric car companies don't boast about their cars having X horsepower. Not many people care about horsepower because either way there are speed limits on the road. I think electric motors should focus on other vectors.

Nitpicking: Nice wasn't part of pre-Revolution France, it joined in the 19th century during the Italian unification.
