Point of order - the electrical grid can be really handy as a navigation aid when walking; it rarely changes (though, perhaps sadly, some long established routes are being buried here in the UK) and is fairly/very visible. Whilst the power line running down your street might not help, the line of towers across the local hillside might be the difference between wandering lost for hours and a fast route out. Map the heck out of it.












The DLR is fully automated, though there is a fold away drivers position for use when necessary. iirc It never runs at street grade and sometimes does have software issues which makes things interesting.
I am pretty sure the victoria line has drivers for show. It was one of the very first lines to be automated and, at the time, it was thought that passengers would panic if there were no driver, so they kept with tradition.
