We were just looking at all of the delivery drivers and the Uber drivers

weaving in and out of the traffic, and that's most of the traffic in central London these days.

We were in one of those vehicles.

They're incredibly heavy and they're constantly tracked and they've got superb alarm systems

so they can't really be tampered with.

But he was saying, you know, if you're in the way, this little voice comes along and says,

please, could you move out of the way I am delivering?

Or words to that effect.

So an awful lot of those delivery drivers will go,

and the driverless car is coming to a city centre near you as well.

So, you know, what jobs do all of those people then get?

And if you look back through all of the previous revolutions, industrial

trying to do. So let's say you had 10 people working on a farm in the 17th century and when

a form of automation came along so it wasn't just the horse and the plough,
