We were fully warned of this with the supply chain disruption of covid.
Global supply chain has become dangerously dependent upon a stable geopolitical environment that has been unnaturally provided by the United States for the last near 100 years in post world war II.
This unipolar naval supremacy is not a normal situation. One of the things that triggered world war I was an escalating arms race in battleships between Germany and Great Britain.
I would recommend the United States practically every country, Force its automobile manufacturers to go very hardcore down the plugin hybrid electric vehicle, which will maximize the battery supply to electrify the largest amount of daily consumer transportation.
I would say you should impose a minimum of 40 to 50 mi for an all-electric range, The 20 mile range which is degraded to really about 12 now is not sufficient in my four phev.
Hybrids also weighs far less gasoline and idling and low torque low RPM situations like stop and go and sitting in traffic jams, by utilizing gener of breaking, using the electric motor for the 0-25 acceleration that ICE engines are incredibly inefficient at.
It's my opinion that the equipment and manufacturing switchover should be much less of an imposition on car manufacturers than the full EV switchover. Consumers do not have such a shocking switch to driving habits because a phev just functions like a normal ICE car if the battery drains, it solves long-range transportation issues and concerns with EVs.
Most car manufacturers know how to make turbocharged high efficiency compact engines, most major manufacturers I believe know how to use Atkinson cycle with variable valve timing combined with a hybrid drivetrain to further boost gas efficiency
