This is a very strange claim from an overlander (assuming you agree with it); surely you're aware that batteries are nowhere near the energy density of chemical fuel, and probably won't be for a long time.

Neither of those vehicles are suitable for 95% of the tasks that people use motorcycles or ATVs for. Googling the existence of something does not qualify you to comment on its usefulness or practicality. You haven't "proved" anything. Once you understand the different varieties of ATVs and motorcycles and their respective use cases, feel free to look for viable electric options again.

Rural areas are not an edge case; they are a large portion of the population. The demographics that constitute HN tend to forget this.

What in the hell are 95% of motorcycles doing that can't be handled by a motorcycle with 108 miles of combined highway/city range? I have plenty of friends who ride motorcycles to work or on the weekend, and aside from not being obnoxiously loud, the motorcycles that company sells would do everything they want save for track days/illegally going 150+ on public streets.

And what are ATVs doing that can't be handled by a vehicle with 500 lbs of load capacity in the bed and can tow 3/4 of a ton? Oh, and it has a range of 50 miles.

I have family that own ATVs, and use them for hunting and fishing, and the Ranger would handle their needs 100% of the time. How many people are taking ATVs out for 50+ mile drives? I guarantee you it isn't 95% of them.

I grew up in a rural area. Maybe not west Texas rural, but Appalachian foothills rural. This ATV would handle just about all the needs of most of the people I knew growing up who wanted an ATV. Heck, the fact that it's quiet, might be a really good thing for them when hunting.

And rural areas ARE an edge case. They're 15% of the US population. Sure, they have special use cases, but your whole "95%" statement is completely false.

And as to the "once you understand the different varieties of ATVs and motorcycles" statement. Electric motorcycles and ATVs don't have to cover 100% of all use cases before they are viable. So stop trying to say they do. There are plenty of areas in which electrics are perfectly viable, and it's probably over 50% today, and it will only continue to grow as battery tech improves.

There is no way on god's earth that Tesla can ramp up production like that. I suspect the first cars that they sell will roll off the VP tools and not off the main lines anyway. With a lack of product maturation the quality of the first cars will be appalling too. I'd bet that the guys at the coal face are wanting to kill their PR people right now for making promises that they know will get broken. Disclosure: work i…

This is not gods earth. I would be interested in how they solved these challenges but you come off being someone who just points out problems which is not as helpful as someone who thinks of solutions, also not as abrasive either.

So is it likely (or even possible) that TSLA really is the most shorted stock on Earth? I've seen this tossed around repeatedly, although perhaps it's just a rumor. On the other hand, > Tesla said that it's now "rare" for a new Model X to have "initial quality problems." [1] doesn't sound very pretty. [1] http://www.cnbc.com/2017/07/03/tesla-delivers-22000-vehicles...

I believe it's in the top 3. Amazon and Alibaba are also contenders.

Disclosure: Short Tesla and Alibaba.

My friend put 100,000 miles on his Tesla in a year and was never stranded. He drove 30,000 miles on a known faulty motor. It's not more unreliable than an ICE vehicle. It's significantly more simple in design and for repair. These claims are FUD.

This seems unbelievable. That is 500 charge discharge cycles at 200 miles apiece. Since there are only 365 days in a year This means that your friend was driving more than 270 miles a day meaning he was at 55 mph that is 5 hours a day. This is on the order of a professional trucker once you count weekends. This also discounts the difficultly of finding well space out chargers. It also discounts the schedule of your f…

Well when someone gets a million dollar settlement from their employer and gets to keep their Tesla paid for outright and has nothing better to do for a year they just drive around the country. So that's what he did.

I'm reminded a little of how the Blackberry board supposedly watched the iPhone announcement and insisted it was fake, as there was "no way" someone could build and profitably sell a phone with that feature-set. Tesla might not do what they're promising. Hell, they probably won't do what they're promising. But pronouncing something impossible on the basis of industry experience can be a dangerous thing. Some things a…

If electric cars are so simple, why is the Tesla Model S so unreliable? https://www.truedelta.com/Tesla-Model-S/reliability-1095 Conversely, the Toyota Prius is one of the most reliable cars. Yet it is mechanically complex with both an internal combustion engine and an electric motor, plus a CVT. So clearly engineering skill and manufacturing quality are bigger factors than the drive train.

Actually the Prius is less mechanically complex than a normal ICE-Car. The planetary gear is really simple and you don't need parts which are prone to wear like a high torque clutch or a complex gearbox.

It is very reliable not despite but because of it's unique powertrain concept.

They will have to setup some kind of timer or incentive to charge off peak, because otherwise, most cars are going to be plugged in around 5 to 6 right when people pull into their garage.

Most cars already do this. In a Chevy Volt and Ford C-MAX Energi, for instance, you tell it what time you leave for work in the morning (say 7:00am), and then it automatically waits to charge until the middle of the night to ensure the battery is full when you leave the next morning. Even if you plug it in right at 5pm, it doesn't actually start drawing electricity until later at night. This feature it set just one t…

Yes, I assumed that the option existed, but I think you are going to see a lot of people who want their car to start charging right when they get home in case they plan to take the car out again that evening or even for emergency issues like what if a child gets sick in the night and the car hasn't started charging yet. Obviously won't be the case for everyone but I can see it being a reason to charge immediately.

My ICE car has regenerative braking. So this is not something exclusive to the EVs.

Really? Don't you need a big electric motor for that... and some substantial lithium ion batteries? Is your ICE car a hybrid?

No, it is not a hybrid. But it uses brake energy regeneration to charge car's battery when you are not accelerating. The effect is not as pronounced as on EV cars, but enough to not use brakes often in normal traffic. In the context of the GP statement, it does reduce some brake pads wear.
