The problem in slow is wheels losing traction, and spinning.

All a high gear does in this scenario is make the car less powerful. When you have nothing else, it might make it less likely a heavy foot will spin the wheels. But it doesn't actually address the issue. Worst of all when one wheel has traction and the other doesn't all you'll get is wheel spin. (In the common case of no limited slip diff.)

Traction control addresses the issue of wheel spin directly, allowing you to apply enough torque to lift the car out of the snow hole it may be in, without one or both of the wheels spinning.

That's not a kludge, that is specifically designed technology doing it's job.

Starting off in a higher gear to avoid wheelspin in the snow/ice isn't an option in an electric car.

Your 20th century kludges are not required. Nor is slipping the clutch or other workarounds for the limitations of ICE cars. Press the accelerator gradually, and an EV will start moving gradually.

"often have a lower total cost of ownership,"

Depends. Not always. Not everywhere. Not for everyone.

Hence "often".

For the vast majority of the population, EV isn't cheaper.

I'd say the exact opposite.

Current IC engines *will* last for hundreds of thousands of miles with nothing more than filters/plugs/oil being changed.

Where "hundreds" equals 2, at best. EVs should easily outdo that - they don't have nearly so many moving parts.

replacing batteries will happen every five - seven years, at a cost that is around $5k - $7k, won't they?

No they won't. Prius has been around for about 15 years, and many of the early models still haven't needed a battery replacement. You're over estimating the longevity of ICE components and underestimating EVs.

The common operations are stuff like tyres, brakes, clutch exhaust, oil change, air & oil filters, and windscreen wipers.

Still need tyre changes. Brake changes much less frequently, due to regenerative breaking. And clutch exhaust, oil change and filters are not needed at all.

In addition there is the need for the occasional battery swap. But probably no more often than the transmission needs swapping in an ICE. And changing the battery is going to be a relatively easy task, given shop lifting gear.

Body work hasn't changed.

It's not that we won't need any mechanics at all. It's just that the work will be much less, so there will be far fewer of them.

I hear some studies say the stock market is a better investment than real estate, while others say the opposite.

The difference of opinion comes about because it depends who you are. For those who work in the investment industry, or have other insider knowledge, the stock market is extremely profitable. But much of those profits are made from the retail investor, who more often than not loses money in the long run.

Overall the stock market goes up, but that doesn't mean the average person has much chance of making any significant money that way.

Property is a much better investment for ordinary people.

On what basis do you make the claim that they are "nicer to drive?

On the basis that everyone that test drives one says the same thing.

I'll put a BMW M3 -- or if you prefer a soft ride a Rolls Royce -- up against a Nissan Leaf any day.

The fact that you have to compare cars from such different classes makes my point. A Tesla is nicer to drive tham an M3. A Nissan Leaf is nicer to drive than a Nissan Versa.

And you have it completely the wrong way around on snow handling. EVs are out in the snow when ICE cars are stuck. It's the low end torque and the extra weight. Don't bother arguing the point, you'll find out if you google.

Biofuels are irrelevant (except for pork barrelling). Virtually all ICE cars run fossil fuels. But when I said in all ways, I clearly didn't just mean the global warming effect. I meant more generally that ICE cars are oily, sooty things.

Current charge times make "recharge when the driver stops for breaks" impossible.

Of course they don't. You don't have to charge an EV from empty to full every time any more than you have to wait for an ICE vehicle to go empty then fill the tank to the top. With an EV the thing is to top it up at every opportunity. The batteries won't be empty, and you don't have to wait till they are full.

And frankly, current ranges on EV's make them pretty much useless for trucks.

EV trucks can carry a lot more batteries than an ICE. The range is whatever you want to make it.

Long distance trucking is probably something that'll come along later, but trucks for local business deliveries is an area that EVs particularly shine in. So much so that some local delivery vehicles have been electric powered for decades, even when the only battery technology available was lead acid.

In the UK the vast majority of the traditional stations have already gone. They've been replaced by stations in the car parks of supermarkets. That's been due to price competition.

But as it happens that's a very good place for EV chargers. You can get a fair top up whilst doing your shopping. Or vice versa. And the charge may well be free so long as you spend enough in store.
