MX-30 is a compliance car. It's a hybrid with the engine ripped out - there's literally huge empty space under the hood, but they haven't even bothered to move things around to make a frunk.

They're taking a loss, and a reputational damage from this. This seems irrational. They could have just left the old software to languish. Could there be more to this? Maybe the Car Thing's DRM has been completely broken? Record c

You address the "personalization" misconception, but to people who don't have this misconception, but are concerned about data retention in a more general sense, this article is unclear and seems self-contradictory.

This is a common misconception that if the kernel needs direct hardware access and such, then it all becomes unsafe. Rust programming style is building safe (zero-cost) abstractions on top of unsafe primitives, turning all other code into s

The downside with plugin hybrids is that they require having a charger at home. Otherwise they're annoying enough that people give up on charging them. This is because smaller batteries take a long time to charge (usually AC only), and

EVs can be charged while parked, and there are nicer destinations to park at. Shopping malls usually are in a better position to add charging, because they already have high-power grid connections, more parking space, and more things to do
939.
by pornel 2y ago
It is possible to split one long charge into two charging stops that take half of the time, but that doesn't increase overall utilization of chargers. EVs are not filled up to full like gas tanks, so a larger "tank" doesn&#x2

You're saying as if it was hypothetical. This is already being done. UK's gridserve has solar farms producing 62GWh/year, that's over 2000 full recharges per day. Their "Electric Forecourts" have 6MWh of batter

You can create a charging station with solar panels and a battery. Gas stations don't fill up themselves out of thin air — a massive infrastructure has been built (and wars fought for) for extraction, refining, and supplying the fuel.

Fast DC chargers add 7 to 13 miles of range per minute (charging is fastest when the battery is almost empty). Competent charging networks also accept contactless cards or even automatically bill your account when you plug in.

In the UK supermarkets have fast chargers. You park, plug in, go shopping, return to a fully charged car (similarly at pubs, cafes, gyms, etc.) BEVs don't have to be plugged in like cellphones. In city driving one full charge can suffi

• BEVs need to be plugged in about once a week (for a median US commute). If you forget one day, you can plug in another day, or day after. • DC fast chargers can add 100 miles of range in 10 minutes.

Batteries are common even in permanent charger installations, because they enable use of cheaper off-peak electricity, and peak charging rates higher than the grid connection.

by pornel 2y ago
Chargers don't have to have higher amps for larger batteries. It's nice to have, but not necessary, and nothing gets worse with a bigger capacity. Rate of charging can stay the same, and it will add about the same range in the sam

This is an empty tautology. You have no insight into the actual design, so I presume your fundamental design flaw is the CDN existing.

Even if the code has been absolutely perfect at the time of writing, growth of the codebase, and changing requirements could make it bad. e.g. if you have 10 items to store, then a simple file may be a pragmatic choice. When it grows to 10,

LLMs have been trained on these answers, and can generate "it depends" too. Sometimes they're even too patronising and non-committal. Chat interface has an advantage of having user-specific context and follow up questions, so
