Piles of Tesla owners stranded at charge stations abandons their EV's.
PlainName:
Surely one would drive within the capabilities of the vehicle. And saving a few bucks may mean the difference between driving and not driving (or, worse, using worn out 'sticky' tyres).

I doubt you can ignore vehicle weight for tire design, especially for aquaplaning.
In the end everything is a compromise.

Even the best driver in the world misjudges their ability from time to time. If I recall correctly the statistic is something like 75% of drivers think they are above-average in their skill. And some things are unpredictable, like someone skidding in front of you or an animal jumping out in front. A good tyre gives you extra margin when things go wrong to stop, especially so in poor conditions.
That is why I always bought good tyres even for my shitty cars.

Amen to that. It is always the people who claim that they drive 'safely' who overlook the fact that while driving you have absolutely no control over the surroundings. Like somebody overlooking a red light and crossing right in front of you. Good tyres are the difference between 'pfew' and a crash. I change my tyres well before they are at the legal limit. As soon as the wear indicators start to get close to the main profile, I have the tyres replaced. The deeper the profile, the better the handling on wet roads.
I have been driving for decades and every now and then people still manage to amaze me by showing some kind of weird ass driving I have not seen before or a situation that hasn't occured to me before. There is always a new surprise behind the corner.

This is the second time I hear this rationalization from you (the previous one was about in context of Leaf's slightly stupid preheat mode losing 1-2% of battery capacity), but I think about it in the exact opposite way: any energy saving gives you more margin against running on "electric fumes". As long as it doesn't involve too big sacrifice on buy price or safety, even 1-2% gains on efficiency are important. At the end of the day, I have somewhere I need to go, and if I had better preheat logic adding 2% and better tires adding 3% then I would arrive at the destination with maybe SoC=20%, which I would be much more comfortable with than 15% because, like you, I hate running on electric fumes. (Actually, 15% is the lowest SoC I have ever ran to on my Leaf, so I have no idea what happens at 0%.)
