Granny loves her G-Wiz

(CNN) -- Transplanted from the U.S to London, Phyllis Earl knows how to get somebody's attention.

I asked the 74-year old grandmother to take me for a ride in her G-Wiz, a tiny two-door electric vehicle that qualifies her for significant transportation cost discounts in a growing number of London neighborhoods.

As she drove the car out onto a major London roadway, feisty Phyllis told me about differences between the United States and English systems for renewing driver's licenses once you hit 70-years old.

"In the States, whenever you renew your license you have to have an eye test. Well, here [in England], they sort of just take your word for it," she says.

As if the prospect of riding in this Coke-can-of-a-car wasn't nerve wracking enough, now I'm wondering if Phyllis - who moved to London in the 1960's -- has anything close to 20/20 vision.

Fear not on both counts, Phyllis handles her G-Wiz with the skills of Lewis Hamilton on a Formula One track. Only a lot slower.

Like many electric battery powered vehicles, the G-Wiz isn't going to set any land speed records or crash into anything at a high speed in London.

But it is tail-pipe emissions free, and as Phyllis told me, she ditched her Ford Fiesta for an electric vehicle almost two years ago -- and says she wouldn't think of going back to a gas/petrol-powered car.

Electric vehicle enthusiasts say with London's notorious traffic congestion issues, there's not much opportunity to put pedal to the metal anyways... an electric vehicle, Phyllis says is ideal for taking her grandkids around town, running errands and visiting friends in London.

To encourage more people like Phyllis to go green, a growing number of local London government councils are offering great perks to electric vehicle owners.

In London's Westminster Council -- for about a $150/year fee, Phyllis gets free parking, a free pass from London's congestion charges, and free access to electric vehicle recharging posts -- called Juice Points.

Westminster Council is installing Juice Points across the London borough to make it easier for electric vehicle owners to "top up" their car batteries.

At least four other London councils are following Westminster's lead, it seems Juice Points may soon pop up all over Greater London.

No surprise then that when Phyllis heard about the electric car incentive program, she wrote a letter to her local councilman requesting a Juice Point be put in her neighborhood.

And in a city where proper customer service, frankly, is elusive -- Westminster Council listened....installing a Juice Point around the corner from Phyllis' home.
