We don't need to start the rumours to see this happen, it will undoubtedly happen at some point for some reason.
Naysayers scaremonger about EVs running out of battery, but what they forget is that there is electricity pretty much everywhere. There are far more public charger locations than there are petrol stations already, even if some of them are a single type 2. Then there are all the people with wall boxes. Six within five minutes walk of my house, that I've noticed. (In addition to the public charge-point.) For comparison the nearest petrol station is nine miles away. If someone had some sort of crisis and was really low on charge, it's likely that a fellow EV driver would help them out with enough to get them onward bound for a tenner.
Then, suppose you have your granny charger in the car, anywhere that has mains electricity is a potential fuel source. It's unlikely to come to that, but the possibility is there.
Given that EVs don't just stop dead when they run out, the way an ICE car will do, and you've got several miles of creep in turtle mode if things get really serious, it's a wonder if anyone actually comes to a halt with a bricked car due to the HV battery going completely flat. There's a video somewhere that says the AA reported that this is "very rare", but even there I wonder if these were early EVs with a very short range.
I've never actually heard an EV driver describe the experience of running out of charge (apart from the guys who have done it on purpose to test the range, and put the results on YouTube). Most ICE drivers have run out of petrol at some point, I reckon. But a stranded EV? I think it must take a very "special" set of circumstances for that to happen.
