The logic is that if a person is mean to their driver, then they're probably going to be mean to the people they work with.

Mr Von Ahn told the podcast that Duolingo had followed through on this.

The BBC asked taxi drivers in London what they thought of the idea.

You get chatting with them.

It's quite a long journey.

People open up to you because they're not likely to ever see you again.

So they can give you little details of what's going on and stuff, yeah.

So you think it's quite a good idea?

Yeah, why not?

Particularly, I guess, if they're paying you to give the judgement.

The practice raises questions about fairness and transparency.

because now that it's public knowledge, applicants are savvy to the consequences of being mean to their driver.

And that's all from us for now.
