Most strikes affecting the underground have not been just drivers, so making the system driverless would be unlikely to change that.

True, and been over safty concerns/reduction in safty staff.

Nicely sums up how the whole driveless tube/train aspect has been rumbling on for a while now.

London's transport strikes have been shown to ultimately benefit the wider economy, as people have broken out of their local maximums and found more efficient ways to travel around.

That you can identify a benefit doesn't mean it's outweighing the costs.

Perhaps the drivers should be paid a sum of money which closer reflects how much marginal value they add to the city, and this would convince them not to strike.
