I'm wondering whether these sales figures are worldwide, or in Japan, or in Australia.
I can kind of see the brand loyalty thing. All the big car makers build the brand loyalty because they know customers want to limit their choice - pick a car from the manufacturer you already know, they probably have a range of vehicle shapes and sizes.
And IMO that's two big reasons why they're also all basically stalling on EVs. Firstly, because they don't have the range of EVs. And therefore secondly EV sales essentially eat into their existing model sales. Dealers hate this because they like selling what they know and they already know what they get out of ICE sales - lots of lovely servicing revenue. And manufacturers hate having to make a new model or redo all the parts, when you can just do a few minor tweaks on the panels of an old frame and make it look like it's fresh and new.
The Japanese car manufacturers in particular have a very good deal where the government has built in a cost to register an old car, specifically to get people to buy new cars and keep pumping money into their car industry.
And I've also heard that the 'honour culture' in Japan makes it difficult for them to not keep the deals they have with the suppliers of parts specific to the ICE engine - spark plugs, cables, ECUs, radiators, hoses, etc. I'm not sure I trust this view entirely, especially since US manufacturers are dragging their heels too and they've been also outsourcing and off-shoring all those things anyway.
To me it just comes down to: sorry, but it's imperative for the future survival of the human race on this planet that we #stopburningstuff . Sorry if that gets in people's faces with brand loyalty and decision headaches. Tough. We have to choose.
