There are many words I'd use to describe an auto-shop. Clean is not among them.

A good shop is clean. Not hospital room clean, not eat-off-the-floor clean, but clean. Floors swept and rinsed, fluids captured in drain pains, etc.

This changing station could well be inside such a tidy and enclosed area at the Tesla Station.

Nitpick: regular kind? That's quite… culture centric. The only "regular" capacity unit that I know of comes from a deliberate attempt to normalize every units. Namely, the Litre from the metric system. Smug Frenchman

It's not my fault that one of the units is just the name of the other unit with a modifier. It's not like "gallon" is shorthand for something longer and more formal.

Hint: when an Englishman walks into a pub, he doesn't order an 'imperial pint' of beer...

imperial gallon & US gallon?

Or maybe more interesting but historical "ale gallon" and "wine gallon".

At 10 gallons per minute, that's still just 2 minutes pumping time. (23 gallons) Edit: I checked again, he pumps for 2.5 minutes and gets exactly 23 gallons. So I guess the pump isn't as fast as Elon says on stage. But it still surprised me because, well, that's about twice as long as what I'm used to :)

Pumps vary dramatically in speed. My car has a 15.8 gallon tank, and it can easily take a couple of minutes to fill up (in Virginia).

Not to mention random pumps that you can never get to pump at full speed because they seem to fail to detect that the nozzle is in your tank's hole, or that click and stop every 3 seconds because the gas backs up because it doesn't flow down the tube fast enough.

The amazing part is that people without a Tesla think that the battery swap stuff is anymore than just window dressing. You charge the car at night and it is full every morning. The times you would use this are vanishingly few. Even on those occasions, unless I am in a huge, huge hurry, I would still take the supercharger over this option.

The cost is fine, about what it costs to fill a gas tank, give or take. But what about this: " Drivers who choose to swap must reclaim their original battery on their return trip or pay the difference in cost for the new pack. " That seems... inconvenient.

Ow. You should be leasing the battery pack from Tesla, and then you swap one pack you are leasing from Tesla with another pack you are leasing from Tesla, so there is no need to worry about what happens when you swap a $8000 battery with a $10,000 battery. (Are the Model S batteries even that cheap?)

Some cursory googling says the cost is probably closer to $30,000. Current purchases can buy a $12,000 future option for a battery replacement in 8 years, so it seems like Tesla's predictions are that even with improvements for 8 years from now, a Tesla S battery will cost $12K+interest.

As Musk points out, this is the fastest pump they could find in their area. Pumps vary tremendously in speed. Actually I'm curious about why the same pumps are sometimes fast, and sometimes very slow. Anybody know? Does tank level really matter that much?

Haha, well if Musk says so it must be true!

In the US, fuel pumps meant for regular sized cars (not trucks, boats, planes, etc) are limited to 10 gallons/minute. If that pump really was that fast, then it really was (among) the fastest legal pump(s) in the area.

Oooh... that's not good. I envisioned it as an insurance-like system: you pay for battery swaps, which cost X amount, which goes toward the collective maintenance of all the batteries in the whole system. Thus you don't have to worry about which battery is yours, or the health of your battery, or anything about the battery anymore. That simplicity alone makes it worth the price of admission. If they're worried about…

That's how I saw it as well. The reality is certainly more disappointing. This would have been a great opportunity to simply take away what I think is the Tesla's most limiting factor: battery degradation.

Its supposed to be drive-thru. If its not, then add opening the garage door (one coming, one going) and waiting in line to the supposed 90-second swap time.
