Power Steering

All of my old cars that had power steering, via a Hydraulic system, came with a warning "never to use full lock". Now as I know a little about Hydraulics I found this warning a little surprising as it should be designed into the system. But what about the TF/F electric method ? Is this clear of the same problems ?:rolleyes2:

I've never heard of such a warning. Any properly designed systems will have stops designed to stop the steering going past the designed perameters.
