These cars has super low emission so they are against to the global warming.In most of the european countries and in the USA, government helps people who buys hybris cars as financial. They don't take tax so it makes hybrid cars more attractive but in Turkey government doesn't help it so, us who cares about global warming cannot buy hybrid cars. There are also other cars that gives less carbondioxide but Turkey must do this tax sale to make these cars attractive.
