As more Tesla Model S's roll out and are in operation there will be a net affect on gas prices - eventually if Tesla keeps up with this trajectory it's going to significantly affect gas prices - Every EV that is sold has a cumulative effect. Tesla Roadster Drives 10 Million Miles and Counting | Press Releases | Tesla Motors The roadster logged 10 million miles in 3 years (2008 to 2011) representing 500,000 gallons of gas.... let's say $3.25 per gal. Thats 1.6million revenue taken away from gas companies. The current tally is 34 million miles... thats 5.5 million in revenue taken away from gas stations from roadsters only We already know there is an estimate of 1 million miles driven by Model S owners approximately 6 months ago. This is going to continue to increase with more S' on the road and the deployment of the supercharger stations. At some point there will be a serious tipping point where there will be an excessive surplus of oil causing problems with gas stations needing to close down and price wars etc etc... wouldn't awesome to see sub $1/gal prices due to the EV revolution started by tesla?
