Before they ban bikes and other small EV's , how about a ban on EV cars then all our lives might be safer. Afaics the rush to rip off follks with expensive EV's is not the answer to our transport needs, some cars don't even need to be in use to be dangerous.
A transporter in Notts on fire with it's load of EV's (hopefully the link works ).

So we carry on using i.c. vehicles and destroy the planet as quickly as possible?
And how are we to get deliveries without vans, increasingly switching to electric? Buses and Trucks too for urban use.
We've created a world where we have to carry on using buses, trucks, vans and cars indefinitely unless we totally redesign and replace everything by going back to a former age of localisation of all supplies in a simpler and less sophisticated world.
That will take at least the two centuries it took to create the mess we are in.
Meanwhile, electric vehicles are a major part of the solution. If you don't believe me ask the railways. Worldwide they abandoned i.c engines long ago.
As for e-car fires, hysterical reporting is not the answer. Governments just need to get a grip of the irresponsible manufacturers like Tesla who use very high capacity cyclindrical cells like 21700 and 18650 in pack formations of several thousands to be able to claim very long ranges combined with very high performance.
That is well known to be very risky and totally unnecessary. One can buy sensible e-cars with sufficient range and moderate performance which are totally free of traction battery fire risk. They use a few hundred physically large but lower density flat cells in a low stress charging and performing environment.
The one I bought almost five years ago (and which is still available) I'll still be using on the original battery in another five years or even ten years time if I am still alive. That won't be going up in flames thanks to using cells designed exclusively for the car job and not those that e-bikes and laptops use which have to be high density and small, so often being stressed and thus more vulnerable to failure.

I've been searching ebay for a good deal on a pair of Quad 405s for years - trouble is being so old, they need maintenance, and many of my local hi-fi repair shops have closed down.

A new discovery indicates that the Aluminum-Sulfur might be the best chemistry for fast-charging, cost-effective and high-density batteries, but there’s a catch

A 12 hour static shot of a slow burning lithium fire at the end of movie care chases of the future, will look very boring. Hydrogen tanks less so, or maybe we'll see ball lightning when supercapacitors discharge?
Perhaps fireproof vacuum vaults will be built under all homes and workplaces, for EV batteries to be lowered into for storage?
"the cause of the fire is unknown"
Maybe they got splashed by a salty wave while travelling along a coast road?
Hurricane Ian results in multiple EV fires in Fla.
The surge of saltwater that pummeled the Gulf Coast during Hurricane Ian caused at least 8 EVs to burst into flames, according to state officials.

Off topic @guerney. Don't the Chinese make (pretty good, no compromise) copies, as they also do with Naim and other amp classics - even down to the case cosmetics?
What you really want is a pair of exposure XVI's - same 100w high current approach and as rare as hens teeth. I bought a new pair, thrashed the nuts off them for ten years, and then sold them on for more than I originally paid.
Will there ever be e-bike classics that make it to collectible/appreciating investment status?
How much heavier are LiFePO4 ebike batteries? If bans are due to increased insurance coverage costs, from my point of view it'd be well worth looking into buying or making one.

Fortunately for my uses (production, a little composition), I only need average sounding speakers and amps for testing, but fantastic quality neutral headphones and studio monitor speakers... but for pleasure, I like the character of certain old amps.
Yes, good point, I really should take the plunge and nab a clone of something epic.
This is my ultimate aim of my Dahon build
I saw a graph the other day that suggested that 42% of the worlds electricity is still being generated by coal. If that is the case, 42% of the energy you're chucking into your EV is still heavily polluting our planet, it's just not polluting your own back garden.
I certainly do invest in renewables (turbines and solar), but everyone changing to EV's is just tinkering at the peripheries. There are far bigger, more important pollutant issues to address first IMHO.
Try Stax electrostatic "earspeakers". They're sublime (and reassuringly expensive).
Like for like LFP is approx. 2/3's lighter then SLA, but still some 25/ 30 % heavier then li-on or li-po.How much heavier are LiFePO4 ebike batteries? If bans are due to increased insurance coverage costs, from my point of view it'd be well worth looking into buying or making one.
Some ebikes used them some 10 years ago but the weight was the factor adding at least an extra 6kg or so to a bikes weight , hence the move over to the less stable li-po and then the better li-on.
The upside is the life of the cells they are some 3 or 4X longer lasting then li-on if looked after . Typically as in the price they look dear but if you consider genuine decent li-on cells for the same capacity battery then price will be little in it.
Comparing like for like in price with li-on isn't easy as the major cell makers don't make LFP so any branded LFP cell will mean little to most of us unless it is an EVE cell.
Kudos bikes were still selling the old work horse Safari step thru with a LFP rack battery but the bike was like 32kg in all. But it was fully equipped with lights, stand , mudguards, lock, panniers and hub gears plus a heavy duty Bafang BPM on the front.

So what? A start has to made somewhere, the alternative is that we just all give up and wait for all biological life to die out?
You are taking an unnecessary gloomy view anyway, not very long ago almost all the world's electrical energy was produced using coal. That it's now down to only 42% despite a vast increase in the amount of electricity produced is little short of a miracle and indicates the huge progress made.
Why not give credit where it is due?
Nor am I contributing to the coal based pollution. My supplier is green energy only so I've been driven mainly by wind power for the last five years.
However, if you end up working your Li-ion cells in the charge/discharge window to prolong cycle life, the capacity for a given weight pretty much balances out. LiFePO4 last many more cycles in the first place and are less bothered by the end of charge voltage compared to Li-ion.
One has to remember the charge and discharge voltage is totally different then li-on/Li-po but pretty much bullet proof safety wise.
I'm actually agreeing with you. Where I do disagree with you is that if you really want to actually help the planet instead of pretending to be "doing your bit", why don't you just get rid of your car altogether (EV or otherwise)? All energy creation is polluting (even turbines, solar, infrastructure et al take energy to create). That your supplier claims to be "green" is crap. Your power is ported into the same energy grid as everyone else; "offsetting" is questionable.
I actually physically got rid of my car last month; I physically put my money (pension) where my mouth is with hard cash investments in Solar, Turbines, and energy storage. I wouldn't for a moment pretend to be truly "green", but at least I'm not kidding myself.
