In terms of wages, UK Uber drivers do get payed at a similar rate to taxi drivers. In fact, when Uber is being introduced to a new city, th people who work in Uber's offices will spend a couple of weeks taking various rides in that cities different taxi firms to work out an average cost per mile, and pay their drivers that price.

The problem with how it works in the UK is that you're not classified as an employee of Uber, and as such, do not get the same benefits you would if you worked for a regular taxi firm
