With President Obama's commitment to combating climate change, it would be a good (if largely symbolic) step for the official White House and Presidential vehicles to be electric cars.
Tesla is an American-owned and American-built manufacturer of electric cars, and they produce a high quality and attractive product.
Hiring them would give a boost to the new electric-car industry, and show that the White House can do more than just *talk* about making lifestyle changes to combat pollution.
