I think that without any kind of justification, this is completely unnecessary for HN, and downmodded you accordingly. Even though I agree that many comments here are one-sided, and haven't considered what the PR statement might be missing.
> Personally, I hope Tesla fail, and think they will.
Maybe, but you need to realize that the electric car is an obvious and timely technological development, and someone will produce a successful mass-market electric car. Why not Tesla? It's not as though they're making a lot of mistakes.
I don't believe electric cars are technologically better. Lugging a half ton battery around, then waiting for hours for it to charge doesn't seem that clever to me.
Of all the things that are banes of our lives these days, surely it's everything that runs on a battery.
Remember when phones would last a week or so on a charge? Now you're lucky if a smart phone lasts a day on standby. And people call it progress...
So no, I think the idea of having a massive battery in my car is horrible.

Early internal combustion engines were also rather embarrassing, but this didn't hinder their adoption -- at the time they were a better choice overall.
Imagine the reverse situation -- imagine that electric cars took hold when they were first introduced in the early 1900s and saw a century of improvements. Then someone comes forward and says, "We have an idea! Instead of charging your battery all the time, you carry a tank of explosive liquid fuel with you wherever you go, and you burn the fuel as you drive."
Present battery technology is pretty terrible -- not very efficient, too heavy, low energy density, short life. But widespread adoption of electric cars will force technological improvements, just as happened with internal combustion engines.
If batteries improve -- greatly -- it will become self-evident that carrying a battery around is a better choice than carrying and burning liquid fuel, both for the environment and in a simple economic sense. At the moment, electric cars aren't an obvious improvement over an internal combustion car, but I think that will change.
In a hypothetical future with more wind and solar energy sources, and possibly fusion power in the long term, electric cars will make more environmental sense as well.
Take an AA battery. Now go back in time 30 years and look at an AA battery.
Identical. Why has battery technology not improved one bit in the last 30 years? Well, obviously there's a massive disincentive - the better the battery, the less people buy, but I don't think that's the main limitation.
I don't think conventional batteries can improve all that much more.
> Take an AA battery. Now go back in time 30 years and look at an AA battery. Identical. Why has battery technology not improved one bit in the last 30 years?
That's completely false. I might have said, "Look at a basic mousetrap 30 years ago. Now look at one today. Identical." What's missing is any examination of the alternatives. 30 years ago, there weren't any NiMH batteries, or commercial lithium-ion batteries (the latter were under active development), but they're now the primary power sources for portable devices, and lithium-ion batteries power the Tesla Model S.
> I don't think conventional batteries can improve all that much more.
And I don't think conventional thinking can improve all that much more. But I have high hopes for unconventional thinking.

> lithium-ion batteries (the latter were under active development), but they're now the primary power sources for portable devices, and lithium-ion batteries power the Tesla Model S.
What does that mean for the user. Do batteries today last twice what they lasted 30 years ago? Nope. Are rechargeable batteries any more viable today? Nope.
Even batteries in laptops only last a year or so before they are just dead and need replacing.
If you think battery technology has really massively improved in the last 30 years, please let me know what real world improvements there have been...
Tesla are actually building cars because the world is running out of oil, so if you want to drive in the future, then the car has to be electric because the price of oil is too expensive.
Firstly, I don't believe electric cars are a good idea.
Secondly, I absolutely hate the idea of cars so dependent on electronics and software.
My neighbour has an old dumper truck he lets me use, probably 50 or 60 years old. It starts every time, first time. There is literally nothing to go wrong on it.
Now contrast that with a modern car, where you need special tools to access the electronics unlock diagnostics. What about when cars have auto update software over wifi? What about when the government forces car makers to embed their own tracking software into them to monitor and spy on civilians.
Tesla isn't quite as bad as the idiotic self drive cars Google is pressing for (So they can drive you to a google advertiser), but they're in the same bucket of nastiness.
Thanks for answering. I respectfully disagree, but we can still have a civilized conversation.

I guess apart from modern safety features and gas guzzling?

Not necessary. People already carry cell phones.
I am actually looking forward to the self driving cars. Human error causes lots of accidents. But then, I don't own a car and probably never will.
