What are you talking about? It's not at all uncommon for married couples to have two cars which are wildly different from each other. Haven't you seen couples where the wife drives some nice, new(er), fancy car, and the husband drives some old POS beater to work? Or where one drives a small econo or sporty car, and the other drives a van or SUV? Why wouldn't it be normal for (while EVs still have limited range and recharging on trips is a PITA) couples to have one nice EV for driving around town, and one possibly somewhat older gas car for the occasional long trip and for one of the partners to drive?

Or, they could have 2 EVs, and a third gas car reserved solely for longer trips. It's not that uncommon for families to have a third car. I knew a bunch of middle-class families while growing up who had three, one rarely used. Or, people could just rent a car. How often do you drive that far away anyway? A few times a year? Enterprise will even bring your rental car to you.

Unless everyone is stupid. Which is admittedly an option when it comes to essential US infrastructure.

It's not just an possibility, it's a certainty if American Slashdotters are any indication. If our "tech nerds" are this backwards-thinking, I think it's safe to assume that the average American is dumber than a box of rocks when it comes to planning for the future.

You don't think people who can afford $75-100k for a car normally have two or more cars anyway? Single under-30 guys aren't Tesla's target market; the people who buy cars like this are older and married. Married people who can afford $100k cars do not make-do with a single car.

It's amazing how out-of-touch you Slashdotters are.

That's irrelevant. The issue is how much power you get with the available feeds. 220V has different feeds available than 110V, and much, much larger ones. With 110V, you're limited to 15A for most circuits, and 20A for some (like the one going to the washing machine). I don't think there's a such thing as a 30A 110V circuit in residential wiring. However, there's 30A and 50A (IIRC) feeds available with 220V. HVAC systems usually have large feeds like that available to them.

So with, for instance, a 30A feed, not only are you getting double the voltage, you're getting double the current of a normal 110V circuit, so that's 4 times the power.

Huh? Converting an automatic car to a manual transmission is almost never a good idea. You're much better off just selling it and buying another (used) model that has the stick-shift from the factory. There's way too many differences between them, especially with modern cars which likely have different engine computers. Even in older cars without the software factor it's a giant PITA.

The newest Prius doesn't look bad at all. However, it's made by Toyota, which has been shown to be incompetent at developing safety-critical firmware.

The SmartCars are butt-ugly, however. And it too little cargo space. The Prius at least seats 4 and has a nice hatchback layout with tons of cargo space.

1) iPads (and tablets in general) will dominate over PCs once they solve the printing and windows compatibility problem (reality: even the latest tablets suck for these tasks, but PCs are in decline while tablets sales are set to overtake overall PC sales).

Tablets are outselling PCs because people already have PCs, and they aren't replacing them every 2-3 years like they did 10-15 years ago. PCs aren't getting noticeably faster, and software isn't getting horribly slower the way it used to, so everyone's just keeping what they have. This doesn't mean PCs are "dying". Go look at cars driving by you on the road; you'll see lots of people driving cars 10+ years old, since cars last a long time now. Are cars "dying"?

but many folks would gladly give up one or all three of those current benefits for a car that can be bought without going to a dealer, accelerates like a bat out of hell and is smooth and silent and gets OTA software updates and support. Tesla intended to disrupt the market and looks like they're doing so very well.

This is exactly correct. Plus, in the transition period, with so many households being dual-vehicle, it's quite likely many/most EV buyers would also own a gas car, probably less used. They'd use the EV for daily stuff, and the gas car for long trips. You don't really need to be able to drive cross-country in an EV.

220V is better for several reasons; not only is it capable of higher currents (with US residential feeds), it's more efficient than 110V since 1) the voltage is higher so you get lower line losses and 2) you're not splitting 220V across a neutral tap on a transformer, and creating an unbalanced load.

1) One needs to be able to charge it quickly, perhaps with an upper limit of about 10 minutes or so,

You don't really need this. When you have an electric car, you plug it in at home and recharge it overnight. Or at work, or some other convenient charging station when you're around town, once these become more ubiquitous. I don't know about you, but I only commute about 30 miles per day. I seriously doubt many people commute more than 100 per day.

If you can afford a $65k-100k car, you very likely have a second car as well. If the second car is a gas car, as it likely is, you don't need extremely long range or fast charging times. Use the gas car for the occasional road trip, and use the Tesla (or other EV) for your daily errands and commutes.

But you're right, once those three points are hit, gas cars are done for. But even before that, there's a market, I think, for people who might want an EV as one of their cars, to use for commuting. If Tesla or someone else made a small, inexpensive (relatively) EV with 100 or 120-mile range, there might be a lot of buyers interested in getting that as their commuter car.

We don't have electricity? What are you smoking?

This isn't like trying to build hydrogen fueling infrastructure, which Pres. Bush was all excited about in the early 2000s. You just plug into the local power grid.

I'm really ashamed to be part of the Slashdot community. You so-called "nerds" are a pathetic bunch of luddites; you're just like buggy engineers who poo-pooed the then-new automobiles.
