Mass hysteria or hysteresis? I can't think what mass hysteresis might be.

Mass hysteresis: vt. The practice of flip-flopping worms for the sake of confusing the readership.

I didn't think it would be recent!
Teslas (in particular) would become unusable. Not that they are usable now!
My view is that the UI should not require the driver to take their eyes off the road, and in particular must not have menus of any kind.
Generally? Perhaps these days, with integrated in-car entertainment / infotainment, but more often I reach for the audio, and get stumped when the big round knob in a Dacia retunes instead of adjusting volume! That's an independent take on the UI nobody asked for!

Absolutely, my Kona N has a huge touchscreen, unfortunately designed for L/H drive vehicles as the top main touch areas for Menu, Back etc. are way over on the left of the display, obviously too difficult to program in the firmware for us in the UK!
Luckily, it has proper buttons and controls for all the everyday things like heating, ventilation, entertainment etc.
Whilst waiting in the car for my wife today I realised the time display had not changed to DST, can't think why, it is sitting there receiving about 20+ sodding satellite signals for the GPS and then I remembered it is a manual setting in one of the sub-menus. Took me several minutes to find it - top far left Menu (quite a stretch even when stationary) - Vehicle - General then scroll down to Enable DST tick box! I would not even think about doing that whilst driving but I am sure many do!
Reminds me of some of the moronic adverts on telly - they show snippets of a car with absolutely all their vastly overpriced options fitted (which you don't want anyway) and then there is the small print text across the bottom of the screen "Car shown is not to UK specification" - well, why are you advertising it then?

GPS knows nothing about DST nor should it.

Presumably because it's much cheaper to film one advert for all jurisdictions and just dub into each language as required. Seems to be what they do. Not just for cars either!

Especially as they are usually left hand drive!

No I know that - what I meant was as the car is receiving 20+ accurate time signals then it should be able to work it out - where it is in the market segment it was designed for - UK model - then set it! All our other recent vehicles have managed it.

Yes, but I think that is misrepresentation - advertising something you cannot buy?

Looks like the fire engine is smaller than the car as well.

Perhaps it is our new "Mini" Fire Service to match the similar "Mini" versions of the Police and NHS we have at the momemt?

Oh yes, their tendency to spontaneous combustion has not been mentioned thus far!

Yes absolutely. There are lies, sorry statistics, going around that in fact there are more fires in ICE vehicles than in EVs based on a percentage of course.
However, my thoughts on that are - if an ICE vehicle catches fire you normally have enough time to get out and get to a safe distance before the fuel tank possibly explodes - a fire in an EV battery pack I understand can create an inferno extremely rapidly with a cluster bomb effect as the individual cells explode and is extremely difficult to control and extinguish.

Indeed. With lithium batteries, it is a run-away reaction and won't be solved until/unless they adopt a different battery technology. Fuel tanks don't explode except in movies (the fuel-air ratio is rarely in the right proportion).
I would be very reluctant to use rapid charging if I owned one (can't say I care much if the EV happens to belong to Enterprise...).
Indeed again, but you won't convince the pro-EV brigade they're being lied to.

Does that mean it is better to fill the fuel tank sooner rather than later so there is less air/vapour?
I generally fill up once it goes under half full for day to day use. For long journeys of course you tend to time refuelling with a loo/food/rest break.

They are building an absolutely huge factory, a few miles away from me, to manufacture EV batteries (presumably Lithium) called "Gravity"! Chinese Industry - Tata Group and UK government (tax payers) money funding this gigafactory of course.
I hope they have some foolproof protection systems built in because if that lot goes up it would affect the gravity around these parts I would think and it might be "tata" to a sizeable area!
None of the blurb mentions anything about recycling old batteries? I thought that was a requirement for manufacturers these days?
Funnily enough the site is built on the location of an old ordnance factory - which of course we have no need for now because everywhere in the world is so peaceful! If that should change we could always launch EV battery packs at the enemy with suitable pyro fuses attached I suppose?

I'll believe figures from fire brigades, and a percentage of EVs vs percentage of ICE vehicles catching fire is the correct way to report this.
As a fire brigade officer said, we've had 100 years to work out how to put out ICE vehicle fires. We'll get there with EV vehicle fires. The latest I saw was a huge fireproof blanket they pull over the entire EV and they just let it burn out. With no external oxygen it burns slower, and it's a lot safer than trying to put foam or other extinguishing materials on it. Also if the cells explode the blanket contains them and they all stay under the blanket.

It already exists. Lithium Cobalt is the one that catches fire and explodes etc. Lithium Iron Phosphate is much less likely to catch fire and is less intense if it ever does. The catch is it only has 80% of the charge density of Lithium Cobalt. Ships with giant batteries use LiFePo because size doesn't matter as much and fires at sea are really bad. Some cars offer multiple battery capacities and the lower ones are often LiFePo.
If you drop a match in a puddle of diesel it goes out, as demonstrated on Top Gear. Does that stop diesel fuel tanks exploding in films? Of course not.
