I am not sure that there is truly a need for dynamic wireless charging.

AIUI, wireless charging is less efficient than being plugged in and dynamic wireless charging would be less efficient again.

Perhaps, if we really put our minds to it, we could come up with a way to make an EV as inefficient as an ICE!

Can I say I think there is a need for it, since it would allow much smaller batteries. The idea with the BEV truck pantograph system is that they only need a battery for slower, quieter roads, then get their power for highway driving from the wires, whilst also refilling batts. If a car could charge 'efficiently' on a 30mph road at 7kW+ then it can start charging rather than discharging. So I see a need, though I'm not sure how important it is. Sorry for the pedantry, as I agree with you.

But, and it's a huge but, can it be done efficiently, and for now I agree 100% with your last sentence, which really made me laugh out loud. Perhaps it's a case of walk first, run later?

What a great way of getting the most use out of the many batteries being produced today for the motor trade. Even at 70% SOC there's still considerable life left in them for less stressful applications so allowing the technology to flourish in areas aside from mainstream motoring applications further down the economic chain and all assisting in contributing to the a cleaner atmosphere we strive for.

Second life project takes off in India with Audi batteries

The German-Indian start-up Nunam wants to put three electric rickshaws on India’s roads that are powered by used batteries from Audi e-tron test vehicles. However, the project goes beyond pure technology.

The stated aim of the project is to explore how modules from high-voltage batteries can be reused after their use in cars and become a second-life use case suitable for everyday use from a technical point of view. But the electric rickshaws also pursue other goals: The electric rickshaws are to be made available to women so that they can participate in trade. If the women can transport their goods safely, their chances of earning a living increase.

Toyota shareholders are revolting!

Toyota faces stern critique from European funds for its lackluster EV strategy

The company has become a stern critic of the rapid transition to all-electric cars. In the UK, Toyota has threatened that it would halt investments in its UK factory, whose production is 80% hybrids, if its technology was banned from the country. This seemed to have been spurred by the UK government’s proposal that over half of all new cars sold in the country should be fully electric by 2028. 

Kiran Aziz, the head of responsible investments at KLP, another Toyota investor, outlined the risks that the company is making by adopting its current stance on EVs. “If Toyota continues with outspoken negative climate lobbying, it will alarm shareholders as such an approach undermines the inevitable transition away from polluting cars,” Aziz said.

... other than the high capital cost. Bear in mind that they are considering diesel trains for the new East-West Rail line from Oxford to Cambridge rather than electrify the line. I'm afraid that this government is obsessed with short-term returns, rather than focussing on long term infrastructure.

Here's an odd one. Article referenced in a Youtube vid of EV news, that made me go look for it. It seems that Hyundai / Kia is to invest almost twice as much money in ICE development and production facilities, as it's putting into EV's despite recent news about them cutting ICE investment.

I have to assume that there's more to the story, as investing ~$42bn in 'expanding' ICE facilities seems somewhat odd.

Hyundai to invest almost $70 billion in South Korea

Hyundai Motor Group has revealed plans to invest 63 trillion won, or $AU69.6 billion, in South Korea over the next three years, with a specific focus on growing its electric car production capabilities.

As part of the investment, the group will commit 21 trillion won ($AU23.2 billion) to the expansion of its electric car production operations in South Korea, with the goal of building 1.44 million EVs a year in the country by 2030.

If achieved, this would account for 45 per cent of the group's electric car production globally.

However, the automaker will also maintain its investment in the development of internal combustion-engined (ICE) cars, with 38 trillion won committed to the expansion of ICE production facilities in South Korea, according to The Korea Herald.

That's despite overseas reports suggesting Hyundai and Kia have paused the development of new petrol and diesel engines, in favour of electric drivetrains.

Why?  It's going to be a long time before a lot of the world has the infrastructure for, or can afford, the current EV offerings.  They are going to want new, efficient ICE cars in the meantime and someone is going to have to supply them.  And it makes sense to make these ICE cars as efficient and as efficiently, as possible.  Or is everyone going to have to drive old ICE rust-buckets and/or 50 mile range Leafs nobody else wants until 2040 (or whenever) ?

Perhaps they are thinking of closing production in other countries e.g. Russia.

That's a good point, could be something like that. Just seems incredible to be spending 10's of $billions on 'expanding' ICE production, when ICEV sales peaked 4 or 5 years ago, and the global fleet of ICEV's may peak this year, before declining as more leave the fleet each year, than are entering.
