Anyone who has phoned for a taxi in Paris has probably used Taxis Bleus. They are now negotiating to have the licencing rules changed to encourage the taxi owners to use electric vehicles. The plan is that they will buy 3-600 Tesla over the next four years.
The present Tesla has no problem with range of performance to meet the Paris average speed of 17kmh and average distance run by taxis of 250kms. The price is an issue, Tesla won't discount but the fuel savings will compensate.
Amsterdam Schipol airport has ordered 167 Tesla for its taxis and New York is approving them as well.
