Re: Trolleyism
Switch to 4G? Don't these people ever look beyond the UK's borders? Even in 1st world countries like the US & Japan, cell systems go down in emergencies. 911, Hurricane Katrina, Hurricane Sandy, Tōhoku earthquake tsunami (also caused the Fukashima meltdown) ... Anyone relying on the cell system was SOL. Often for days, in some places weeks or even months.
Obviously, no major disasters could ever happen in the UK, so no problem.
