Average life of ICE vehicles can't be 266kkm, that's absurdly low. Most of people I know have bought vehicles with that mileage and used it for another 100kkm after that at some point in their life (think first/second car, second family car, etc.). It's important to know that especially in Central/Eastern Europe, you can never trust the car's odometer - even the cars I'm talking about had probably more than 350kkm wh…

> Average life of ICE vehicles can't be 266kkm, that's absurdly low. People buy a lot of Chryslers, Fiats, Fords, and Chevys. You'd be lucky (or cursed, depending on how much you hate the car) to make it to 266kkm with a Chrysler Sebring, for instance.

Sebrings, as I recall, require either completely removing the front left tire, or pulling the wheels to the left as far as they go in order to remove the battery, which is housed under the wheel well.

Not everyone builds Corollas.

I'm curious at to when that example would ever be suitable; memory sizes should be grouped in 3s as well. The only one I can think of is phone numbers, e.g. Australia is a 4-3-3 grouping for mobiles. But a space has been the standard delimiter there anyway.

Dashes were "the standard delimiter" for a long time for Australian phone numbers. 451-4153 was my phone number growing up (and yeah, I'm showing my age with a seven digit phone number... A friend of mine was on 99-0066 up until the early or mid '90...)

Interesting. As a contra data point, I grew up in Sydney with 86 2050 as our landline (as if there were any other types of line! :) and I never saw hyphens used within phone numbers. I worked for Telstra during most of the 1990's, and didn't see it in use there either. Might be a regional thing? I note that our North American cousins enjoy splattering hyphens through their phone numbers. I like the space approach.

Frankly it might be a bit confusing to Canadians, here we use the U.S. numeric conventions, but we tend to use a mix of SI and imperial units, and in this case we'd use kilometres for ground distance, with thousands separated by commas. The UK also seems to prefer commas to separate thousands. I'm inoculated against confusion about this because I've done a lot of software and content localization, and have a grasp on…

I'm always surprised that en_CA and fr_CA are so different. We use spaces as separator and comma for the decimal. Also we use the 24h format while the ROC uses 12h. We do use 12h colloquially though. Dates are officially y-M-d but most people use d/M/y. It's funny how in Canada we have some specific remnants of the imperial system. Most people under 50 have no idea what a Fahrenheit is (myself included), except for p…

The funny thing about the imperial remnants is that for almost all general tasks, Canadians still use pounds for weight (groceries, body mass, vehicle weight), but we don't use ounces. We use feet and inches to measure people, but metres for almost everything else, except nautical speed. Litres for gas in cars, sometimes gallons or pounds instead of litres for gas on boats. Pints for blood and beer, ounces for hard liquor, litres for all other service and retail fluids.

People complain about inconsistency and lack of standards in the use of measurements in the U.S, but it is actually much more consistent there. It turns out that decimal units aren't really better for any practical purpose in a typical person's life, and it's certainly worse if you need to know both!

Even in the U.S. of course, engineers, mechanics, plumbers and others still have to deal with a mix. Think metric-based and imperial-based bolts, metric v. imperial lumber sizing.

I'm just over here patiently awaiting some startup to unseat Tesla as the king of speedy, luxury, electric automotive. Nobody is quite taking the cake, or even trying for that matter.

There are at least a dozen companies trying to do exactly that. Thing is, Tesla was exceptionally lucky, and it is still incredibly hard to build a car company. Tesla managed to squeak through to the Model S, which was absolutely critical.

For companies that are trying to make a Tesla killer, they have to hit the price point above a Model S with zero volume. That's means no factory and hand building almost everything. That destroys any ability to price reasonably. Tesla killers start at 300k and range up to 2 million. Nobody at that price point wants electric cars right now, or at least very few people. It doesn't come with the same bragging rights as a Ferrari or Koenigsegg. Those have brand and absolute, vastly supreme performance respectively.

Also, I suspect people are aware that as soon as Tesla announces a new roadster the game will be over. Nobody will want to buy anything else.

That's quite impressive. What I am wondering is why they do do well, barely losing 10% in 5 years, compared to phone or laptop batteries that last maybe 3 years on average. AFAIK, they use the same technology, in fact, I wouldn't be surprised if the same batch of cells end up partly in Teslas and partly in laptops.

The real killer for laptop batteries is the fact that they are kept at 100% charge plugged in while under extreme thermal stress. Temperature + full charge kills li-ion batteries. Do your laptop a favor and never charge to 100% unless you really need to.

Really? If this was the case, I would expect laptop providers to allow you to set a top charge rate for those like me who have their laptop plugged in 90% of the time.

Some do (ThinkPads).

To Apple MAC developers: can we get this feature?

Add one or two zeroes at the end and i'd guess we'll be more in the ballpark..
