I should have stated "electric vehicles" vs "electric cars".
However you really don't have the slightest idea about the motor that's in the Tesla. Which is a 3 phase induction motor. There's a lot that goes into converting DC battery power to AC and then controlling the torque. Heat is another issue that will have to be dealt with as well and the latest announcement from Tesla is that they will be adding a water cooled system to the induction motors in the future.
A property serviced gas motor doesn't need much more beyond oil and spark plug changes and can last for several hundreds of thousands of miles. The majority of the consumables are in the wheel systems, tires, brakes, suspension, bearings, heating and cooling the cabin, etc.
I'm sure you're an idealistic kid that thinks green is good... and knows that ignition=starting, but the fact remains that gas engines have a 100 years of service history and electric car motors don't which means...
>I'm sure you're an idealistic kid that thinks green is good
I am the engineering manager for the Australian branch of one of the world's largest oil and gas contractors. I graduated with 1st class honours in mechanical engineering, and have 25 years of work experience. Idealistic - yes, thinks green is good - yes, my career notwithstanding. Kid - I wish...

Actually, I have a pretty good idea about both of these things. A really very good idea in fact, helped a bit by my visit last week to the factories that make high speed AC motors and inverters that drive them.
well hey... I thought the ignition/starting thing was funny. I like the idea of green too. I don't see tesla as green. the tech isn't there yet. and if you've been on this planet as long as I have... you know there is NOTHING revolutionary about induction motors (circa 1889) or lithium batteries(circa 1979)... I don't like the idea of highly subsidized innovation. If products can't stand on their own... forcing them down the consumers throat doesn't make them better.
