@reuters article on #Toyota talks of a possible reboot of it's EV strategy because it's present mixed EV/ICE manufacturing strategy just can't compete with Tesla lower cost pure EV platform. reuters.com/business/autos… To compete you have to make a compelling product and to make it at volumes and costs that are profitable.

Right now Toyota is loosing at all 3 when competing with Tesla, and Toyota's tactic of delay and FUD to slow BEV growth hasn't worked sufficiently to stop them breaking out.

I have checked in improvements to #VulkanScneneGraph shader composition support so that now a range of shader variants can be pre-compiled to SPIR-V and built as part of the library itself:

github.com/vsg-dev/Vulkan…

This can mean no more loading and compiling shaders at runtime! Shader composition might at first seem like another layer of complexity on top of GLSL shaders, but it actually makes shader and C++ code management easier once you understand how to use it.

To explain the improvements I've started a thread on vsg-users:

@AlefAeronautics debut a novel Flying Car, aim for it to be capable of VTOL so capable of flying without needing a runway.

Personally I think even it works it'll neither make a good car, or a good aircraft, but then I've yet to see any design that might be good at both. @AlefAeronautics This is the launch video (with fixed audio as the original launch video had screwed up audio) :



Even without the original audio fail the presentation still doesn't inspire much confidence there will be a vehicle on sale in 2025.

Bosch’s chief executive Volkmar Denner said “We need combustion engines. We need to build combustion engines. We need to have them on the road, And that’s a fact.”

"We" being Bosch, fact is rest of humanity need to get away from combustion engines ASAP.
ft.com/content/924758… The status quo coupling between Profits and Pollution needs to inverted.

The likes of Tesla show that it's possible to increase profits without causing life long pollution from use of it's products.

The likes of Bosch execs try to tell us that's not possible nor desirable.

Sounds like Hyundai are going all in on electric drivetrains:

"Hyundai Motor Co., the group’s larger carmaker, closed its engine development division at its research and development center, according to industry sources on Dec. 23. "

kedglobal.com/newsView/ked20… And... "has fallen short of virtually every target they had for fuel cell vehicles. Production and sales are lower than expected, cost is falling slower than expected, infrastructure is being built slower than expected, and hydrogen fuel prices are higher"
