Where is my "thseis statement"?

In everybody’s life must had an experience of taking the taxi. Taxi is a very common and useful public transportation around the world. Thought the price of the taxi is more expensive than other public transportations, such as bus, MRT, and train; taxi is still very popular for people who are in a hurry. There are other reasons that people in the world will take the taxi. For examples, someone who can not catch the last bus, who hates to be crowded, or someone lost their way in the unfamiliar cities. For myself, I will take the taxi about ten times a year. Although my experience of taking the taxi is not often I still figured out the different types of the taxi drivers. There are six types of the taxi drivers in my opinion: the talkative drivers, the cautious drivers, the crazy drivers, the greedy drivers, the overbearing drivers, and the taxi drivers who have no sense of direction.

Above is the first pargraph of the essay, and I don't know which sentence is the thesis statement. I'm practicing writing thesis statement so I need help. If I did not point out the thesis statement then how can I wirte it? (Many grammatical mistakes)

To AlpheccaStars, I only want to write about the different types of the taxi drivers.
