This sign greeted me earlier

Pay with the app … but only when you’re inside your car. Long ago it was thought that a mobile phone could cause a spark at a petrol station (one would imagine a far greater chance of that with vehicles moving through the petrol station of course).
Now it seems to be to avoid people being distracted – staring at their phone as another car bears down on them perhaps.
We don’t really need this sign in petrol stations – we need it at zebra crossings, on stairs to and from tube stations, on every pavement in the land etc.
But, of course, we would all ignore it in those places too.
When petrol and diesel pumps are replaced by EV chargers … will we still worry about mobile phones causing sparks and being a source of distraction?
