Citation needed. I would think most taxi drivers are smart enough to figure out that it is better to work a few more hours more on rainy days and sit in the park on sunny days than to work a few hours more on sunny days and sit in the park on rainy days.
You got one. 'Thinking Fast and Slow' by Daniel Kahneman. Sometimes people don't optimize long term and just prefer to get 'daily' rate and go back to their families. This might turn bad if sth happens and they can't ride for some time and could use the 'rain' money. Book is really good, highly recommended.
