This topic is for postings of first reviews to psych ourselves up even further, and to divulge tidbits of information that have otherwise not been widely discussed.

Tidbit 1: the car uses an accelerometer to tell itself when to put on the brakelights when slowing using regen (brilliant).
Tidbit 2: each display is powered by Tesla's own OS running on a Tegra 3 SoC -- both computers communicate via Ethernet and a gateway provides an interface with the vehicle's ECU.
Tidbit 3: the screen is easy to read in direct sunlight.
Now have at it everyone!
Here is a list from TMC courtesy of loganss:
I don't get the accelerometer thing. Based on the slowing rotation of the wheels, the car could easily compute the deceleration. Why use an additional component ?
Since it has single fixed gear and PEM is computerized I bet the brake lights use information from there. That would be easiest point to retrieve deceleration info.
Using an accelerometer might be a safety feature, it makes sure the brake lights work even if the computers are dead.
Accelerometers are dirt cheap. About 2 bucks. Speed sensors on the wheels have to work in a dirty environment, and require computation. How fast was I just going, vs how fast am I going now, what's the difference over how much time. Then it can calculate decelleration. Or you could just measure it directly... Speed sensors make the problem more complex than it needs to be.
Also, should someone install different diameter tires, the rotation of the wheels wouldn't be very accurate.
If PEM breaks down your car stops. I think that is far more reliable than any additional sensor.
found a review of an European jounalist in German

Will this comment get posted? The other one I'm trying keeps getting errors that the site it under maintenance.
For your amusement, I posted a reverse German translation of the Google Translation into English here: http://www.teslamotors.com/en_CA/forum/forums/german%E2%86%92english%E2%...
By the way, your application of the article rule for a/an needs adjusting. A sub-rule says that words beginning with the 'y' sound, as in young or yellow, are treated as starting with a consonant.
So: an eerie moment
-- but --
a young man
a yellow hat
a European country
The "Eu" in Europe in German sounds like the "oi" in "oil" to us, but we pronounce it as "y", as in "yearn". So it takes the consonant article, "a", not "an".
Thank you ;)
English is weird. The "definite article" rule is fuzzier. There are two pronunciations of "the":
before a vowel, it is sounded "thee", but before a consonant, as "thuh".
However, either works with "European". Either "thee European economy" or "thuh European economy" is OK. I forget the formal rationale for it.
Sorry, that was for NV (Norbert.Vienna). Nota Bene!
BTW, Norbert, how does the German back translation read to you? The English Google version borders on the incomprehensible in places.
its partly not understandable anymore
actually a word by word translation is not possible
especially the writer is using words which are Autrian slang expressions
to sum up the article represents the comman opinion
the Model S is a great great car and as soon as it will come to Europe it will set new standarts here too
there are critics on the interior as already spellt out in the forum here
@ rowantrollope - nice review. Thanks for sharing. All of your negatives seem to be fixable in future releases. Except of course for the typeface heartbreak. That may take serious reengineering. :-)
Heh. The typeface is not gonna change. It's a "branding" issue, now, and once the marketeers get their brains infected with a "branding" meme, the condition is terminal.
