The chairman of Ford Motor Company says he doesn't think that a drop in oil prices will dissuade people from buying fuel-efficient vehicles.

Bill Ford, the great-grandson of company founder Henry Ford, says the firm will continue to push for green technology in cars.

He was speaking to a select group of media in the United Arab Emirates on Wednesday, where the company recently established a business unit to serve the Middle East and Africa.

Ford also gave a speech to a wider audience about his vision for the future. The Ford chairman has for several years been warning about gridlock traffic in the world's major cities and says what's needed is a "leap in thinking" to develop technology that would help alleviate congestion.
