The best way to describe corporations is that they are like steering massive cruise ships. When you see the icebergs ahead, you need to make those steering inputs early, not late, because late is often too late.
One problem with Toyota and Honda is that they do not control the supply chain, but of course, none does completely, unlike BYD, who makes its own batteries and designs its own chips (fabless chipmaker). This is where the monster analogy comes in. If you want to be a force in the field five years from now, now is the time you better start creating your supply chain.
Car wars is all about margin wars. If you are only making a profit out of a few hundred dollars a car, margin control is essential and for that to happen, you need a tight grip of your supply chain. If you make your own batteries for example, your cost would be lower than if you have to buy it from someone else.
With CATL dominating Lithium Iron Phosphate for example, and LIP batteries is becoming increasingly the cost for the low end EV for its low costs and safety, how is Toyota and Honda going to source them? I don't think Panasonic makes LIP. Look at GM, which sourced batteries from LG Chem, and what a flaming wreck the Chevy Volt has become. Fact is EV batteries is a very safety sensitive issue and requires multiple levels of testing. I have yet to see anyone claiming that ramming a nail through their battery won't make it explode unlike the BYD Blade battery, which I believe is a major game changer. I also see the Chinese battery makers, CATL and BYD especially, leading the charge for cobalt free battery already tested and ready to deploy them, when others like Panasonic and LG Chem, are still using nickel and cobalt. We're talking about an advantage that is in years.
