Ok, but what is the French view on whether substance is a desirable component of communication?

The same technology for defence purposes is available from here: https://esoxgroup.com/

Have you seen any French films?

> I can confidently say that every one of them would love EVs if [...] And I can confidently say I see rural pickup owners rolling coal about weekly, so no, they will not be loving EVs, because it hampers them destroying their surroundings.

As I said, I am only talking about people I know personally. Not everyone is like that, please stop lumping everyone together.

Not everyone who dislikes EV’s is doing so irrationally. Not every one of them is a moronic anti-environmentalist. Most people are just trying to get by and they’re looking at what they think is best for them. Thinking everyone who disagrees with you must be a backwards coal-rolling moron is… not a great approach. You can do better.

Even as things currently stand, some folks just have a bone to pick with EVs. Even if future models have an 800mi range, can charge to 100% in 5 minutes, and have useful lifetimes as long or longer than ICE counterparts, some will figure out some reason to get angry about them.

It’s range anxiety and it’s real. And it’s not entirely unjustified. Where I live in the Midwest I have literally never seen a public charging station. I know they exist because I can search for them on maps app and I see dots, but it speaks to their general small numbers that I’ve never seen one in person that I can remember. Now, prior to this, I lived in California for many years from 2011 until 2019, and I saw to…

With my plugin hybrid I have currently the best of both worlds. The 2x25km commuting is electric, and longer weekend drives are gas. And being in Europe, I am not worried about charging stations for whenever I'll switch to full electric - I enjoy taking gas station breaks. I know it's only one data point, but it's my data point :)

The biggest issue is that people think EV's are gas cars that have electricity instead of gasoline, with the main difference being you have to sit at the "gas pump" for 45 minutes instead of 2. But the way you daily an EV is totally different than a gas car, and even the way you travel is totally different. People have no concept of EV ownership, so they just go with the gas model that they know. But it is totally in…

If you don’t live in a conventional house with access to overnight charging, this is exactly what EV’s are. But we keep talking down to people like this, as if every non-EV owner must just be stupid or something.

A person I know is upset about EVs because they are built around the assumption that every system in the car will phone home to the car manufacturer (or perhaps the cops), and basically require you to have a proprietary smartphone app in order to interact with EV chargers and perhaps the car itself. Of course, this is also true of new ICE cars, but it's at least possible to continue driving an older ICE car with more…

My concerns are the computerization of vehicles in general. The issue is not entirely with the telemetry itself, as you frame it. My issue is "what happens when the telemetry is not available?" You, and perhaps your friend, seem to be framing the problem as though the concern is that the car is filled with "spyware." My issue is that the car is filled with "DRM" from the manufacturer. When I buy a car, I expect to ow…

In armageddon, you would run out of fuel around day 3 and then that's it.

A CyberTruck will charge just fine from anything that can generate the proper AC or DC, no phoning home needed. Many home solar installations can work off grid and charge your car.

Here some info about the claim of 600km/344m range of Verge motor cycles as it was said and shown in the video. The website of Verge bikes states the following:

City estimate 600km: "The city estimate calculated by Verge aims to provide a reasonable approximation of calm stop-and-go riding in an urban environment at low speeds. The estimate assumes a 75 kg rider and ideal riding conditions in terms of temperature, wind and tire pressure. Actual range varies based on exact riding conditions, riding style and other factors."

Highway estimate 315km: "The highway estimate calculated by Verge aims to provide a reasonable approximation of steady and consistent highway riding at a speed of 90 km/h. The estimate assumes a 75 kg rider and ideal riding conditions in terms of temperature, wind and tire pressure."

Now: "aims to provide a reasonable approximation" is legalese for "we pulled these numbers out of thin air - they are in no way legally binding".

For proper testing according to "EU Regulation 134/2014, Annex VII" the website says 'TBC'. This would be legally binding but -surprise, surprise- they haven't yet found time to do it.

For any practical purpose the range will be between 200km to 250km. Also the bike is not easy to handle due to the high mass distribution to the outside of the wheel.

Btw, the vendor from Verge motorcycles states in the video 80% charge in "about 10 minutes" instead of 100% in 5min. So which one is true? I stand by my claim that this is marketing for gullible buyers and investors.
