> Audi's Super Bowl ad also gave lift to personal transporters

The Audi commercial that topped USA TODAY's Super Bowl Ad Meter among automakers for best-liked ad apparently might not just be selling A3 TDI diesel cars. It could have provided a boost to the company that makes those three-wheel personal transporters that cops use in airports.

T3 Motion, a company in Costa Mesa, Calif., had its electric vehicle in the commercial, in which the "Green Police" are seen harassing people who don't recycle or try to cut their carbon emissions. The T3 is a Green Police transport vehicle.

In the real world, T3 Motion's transporter is used by lots of different agencies, from law enforcement to event crowd management.
