Electric cars have become more popular with environmentalists and the general population with each passing generation. The sustainable green cars are now being produced in larger numbers than ever before and by a variety of automobile companies. Some of them even come up with rather unique tie ups that can be fun for the people.

This is what a company called Fortum, a taxi service in Finland is hoping to do. Create more awareness and have fun, as passengers in the taxi service are allowed to pay for their cab ride with karaoke singing. Scheduled for the three days of the Ruisrock Festival, passengers traveling in Fortum cabs will have the option to carpool and karaoke to their destination.

Fortum is sponsoring a series of BMW electric cars and transforming them into a fleet of clean energy, emission free taxis. The Singalong Shuttles hope to shine the light on smart solutions for the future. They hope that the passengers realize just how much fun it can be to sing with no engine noise in the background, considering how silent electric car motors are.

Now this is one science experiment I endorse wholeheartedly. Wouldn’t you love to sing for your taxi ride as well?
