Producing electricity, largely isn't green. So the concept is fairly flawed no?
However, it looks nice enough and I'm sure will be a fun toy for some rich yanks.
I can't imagine electric cars ever being as fun though for enthusiasts, although at least the performance is making strides.

Not really...think about the "emissions" saved from the currents petrol/diesel cars?
Also, the transport/production/mining/distilling of Oil for said diesel/petrol cars...
Look on the bright side, the government can't charge for congestion and CO2 tax? can they?! do you think they will do grant/bursaries for leccy car owners? much like people who wanted to adopt solar panels.

It's not 'saved' though is it? you're still burning the fossil fuels, the only difference is the emissions are moved from the roads to the power plants.
Depends how the electricity is farmed.

Going on the theory that all available fossil fuels will be burned at some point in the future, nothing we do makes any difference surely?
We're not suddenly going to start leaving oil in the ground, so it'll get burned, and release CO2.

If we discovered free energy then we might just leave a little bit left, as we would only use oil for plastic bags (which I am sure has paper alternatives).
But burning a high percentage of fuel at once (lots of petrol/diesel cars) is more likely to make an effect on the environment than burning it a small percentage (more electric cars, but more powerplants) over a long period of time surely?
i think there is more nasty stuff in its batteries, and realeased when making its batteries than it'd release if it had a proper engine

Plastic bags is the easiest thing to phase out the use of plastics. The aero industry is being pushed to go green, but all the carbon fibre components now being used require a huge amount of oil in making the carbon and the epoxy resins.
Then theres things like pens, clothes, furniture, white goods....
Either I'm totally wrong or the Tesla can drain its batteries in just over 16 minutes at full whack.
The batteries when fully charged hold 53KWh of charge (to begin with - max charge will reduce as the batteries are discharged/recharged).
The motor can put out 185KW and is 95% efficient, so it can pull 195KW from the batteries.
That gives 16m18s to drain the battery pack.
OK, you wouldn't be using full power constantly for 16 minutes, but you're not going to want to show off the acceleration repeatedly and a track day would be a bad plan. You'd have to drive very carefully to get a 200 mile range.

The idea is that power station efficiency - transmission losses - charging losses > car petrol/diesel engine efficiency.
I'm not sold on the idea. Maybe in places that use a lot of solar/wind/hydro/geothermal/whatever, maybe nuclear too (no emissions, just radioactivity).
