The 2030 timetable is not going to be met by any single manufacturer, if it is going to be met to begin with. I suspect that it is going to be pushed backwards bit by bit as reality sets in: that it always was too ambitious a target to realistically achieve. And if they stick to it, which I would find very brave it will simply mean that the price of personal transportation will skyrocket and that older non BEVs will have to hang around a little longer.
There is so much that has to work for an all electric transition for every new vehicle sold in the next 7 years to be successful that I wouldn't bet on it. I think of it more as a goal to strive for than something that is realistically achievable, but of course I hope that I'll be wrong on this. Time will tell.
Also keep in mind that whatever goals have been set that Europe at a minimum (but probably also other territories) are going to want to have a very large slice of the labor/manufacturing pie. If that isn't on offer then the tariffs will likely kill the market to protect local competitors, of which there are plenty.
Apple was a well known brand name before Nokia was, and that is in part why it succeeded.
The car industry, specifically the American market, already went through the "nobody can do tha-- wait what" phase once upon a time: California was poised to enact then-considered-ridiculous emissions regulations, American car makers all complained it was impossible to satisfy and California was on the verge of shelving them when Japanese car makers (read: Honda) came in to show it can be done.
The rest is history: Japan proceeded to murder and dominate the American car market, and soon the world.
The moral to take away from that is that so long as even one manufacturer can demonstrate the feasibility of the timetable, they can and will become the new king and kingmaker of the car industry.
I'm in fact in complete agreement with you that the 2030 timetable is ridiculous and it'll probably be pushed back and back with excuses, but history has proven itself to be amusing at times.
