Every taxi I've taken in the last 5-6 years has built in cameras that film both the back seat and the passenger before pickup. There notices but I don't believe you can assume privacy from the driver when it's not a limo with the screen up or something similar.
There are legitimate reasons why this is done in a taxi: preventing people running away from payment, engaging in harassment or other bad behavior, or claiming you refused to pick them up for reason X when you had a good reason to not pick them up. From what I know of Uber, these reasons all apply to their drivers as well.
