When you are there press and hold down the X button. Get out of the taxi while you are holding X, with Y. Keeping holding X and get inside your favorite car. When your character is in the car waiting, unleash the X button. Make sure you do not unleash the X button while you character is opening the car. Now the game thinks you are inside a taxi, good job.
