Texas only got open carry a little while ago. Their whole reputation with guns is a hyperbolic fantasy, many northern and blue states have always had less restrictive firearm laws.

So what? Not everyone wants to live in a communist hellscape where everything is regulated to death.

Most actual communists support civilian gun ownership, Karl Marx was himself a big fan of a well armed working class.

It is authoritarians that want gun control the most because they want a monopoly on force through the military and police.

The problem for electric motorcycles is the battery weight.

That can be offset by not requiring the same sort of range that's typically assumed to be required. While I'll be likely be riding my ICE bikes for decades because one of the things I do on them is trips with 1000 or 1500km days, truth is the vast majority of my riding is sub 25km round trips from my place. Most of my friends places, a lot of the places I shop or socialise, and the office (which I pretty much never g…

It really can't be offset by that (with current tech). All existing electric motorcycles are both overweight and very limited on range.

Americans do not do metric. Americans can’t even balance a checkbook. Hence the small dog reference for mental “clarity”. We’re dumb. Just look at the news…

Sure but don't they have a mental image for 80 feet for example? Why articles will almost always include something like "that like 50 chairs put next to each other" when length is mentioned.

I would say most American's sense of feet gets fuzzy after about 30, there are very few things that are standardized that size or bigger or that they have ever personally measured out. Yards might be more useful up to maybe 200 or 300 because they have all seen football fields though. After that for most people they go to miles or minutes of travel.

Some farmers might throw in a reference to an acre length that is referencing the 660 foot length of a standard acre (660 feet x 66 feet, or 1 furlong x 1 chain), which is just another way to say 1/8th of a mile.

Everything but the Metric System: “The new YASA axial flux motor weighs just 28 pounds, or about the same as a small dog.” :)

Americans are very weird when it comes to metric. They often quote mobile phones as having something like "a six inch screen size but now only 12mm thick" - pick a measurement system people !

I like having more choices for units. Sometimes the "correct" unit is extremely inconvient to deal with, either because the unit sizes are oddly out of proportion with the things being measured, or the things being measured have odd ratios with the units. Sometimes even making your own unit system or going with pure ratio relationships between objects is the most useful and effective way to measure things. And I feel that people who only ever use a single system of measurement often fail to see it and put themselves at a large disadvantage.

To me using only a single system of measurement is the same as only ever using a single number base. Yeah it helps to have a standard number base everyone can use like base 10, but that doesn't mean we should try to eliminate other number bases from our vocabulary or understanding because they obviously have situational advantages.

Also from my personal bias I much prefer fractional measurements and people go apeshit if you use fractional metric units but don't blink an eye at fractional imperial or other 'non-standard' measurements.

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.

People only stopped caring about horsepower recently because it became so cheap that everyone has more than they can utilize. HP use to be an important metric in a car because it was the main limiting factor in speed and capacity. Today engine power is rarely the top limiting factor, the tires, suspension, transmission, and driver ability are far more important, but far harder to quantify for marketting bulletpoints.

This discussion is all about vehicles with large batteries, but how about hybrids? With light enough and efficient enough motors, all kinds of designs might become practical: - Toyota-style hybrid drives could be a lot lighter, and they don’t need large batteries. - e-bikes with tiny batteries? - Hybrid aircraft? What if there was a battery large enough for takeoff and landing, a small motor (or pair for redundancy)…

Guess Lamborghini uses them:

Technically a hybrid but probably not what you had in mind?

I see kids blasting around at high speeds without helmets. Kids treat them like fast bikes you do not have to pedal. Wiping out on a bike at 13mph is a very different proposition to wiping out on a bike at higher speeds. I saw just a couple nights ago some kid doing what appeared to be about 40mph on an eBike. Wind in his hair, not pedaling, just blasting it. I am sure new regulations will come to speed limit them, b…

On a decent hill you can get a regular bike going >60mph. A dirt bike will let you ride off road at nice speeds over random terrain (no licensing required when not on public roads). In the realm of bikes, these are not an outlier. Limiters are easily overcome and speed limits are barely enforced on cars, let alone bikes. When you get a bike like this you deal with the danger and wear protective gear just like you wou…

Sure, there exist hills where some reckless people who refuse to brake can hit 60mph/100kph on a classical (non-motorized) bicycle. Unfortunately it’s difficult to prevent such stupid behavior, but thankfully, the places where it can happen are severely limited.

Therefore, we should count our blessings that it’s not more common, rather than allowing devices that enable it.

That’s completely unrelated to whether these bikes are safe. HN articles are not part of some zero-sum competition between the US and Europe.

Right, so they sell guns at a super market? Walmart is a super market and like you say, they sell guns. How is this "not really"?

Walmart isn’t a supermarket, it’s a hypermarket, which isn’t really the same thing. This isn’t specifically a US distinction: it would also not be called a “supermarché” in France for example.

Most of them do have a (relatively small) grocery section, but are primarily dedicated to non-consumables like clothes, children’s toys, furniture, electronics, etc.

Whereas a typical supermarket (e.g. Safeway, Fry’s, Albertsons, Whole Foods etc.) might have a relatively small section of all of the above, but are primarily dedicated to food.
