None of the basic problems have been solved.
The “magic tipping point” is government mandates, tax rebates, subsidies, and purchases by government for their own fleets of vehicles. The “tipping point” is selling folks a terd by relentlessly advertising with ideas of zero emissions, green, sustainable, and other nonsense.
The basic problems of the EV has been and remains the battery.
1. A batteries power density sucks: lots of weight with little energy and lots of volume with little energy.
2. Batteries have a very finite cycle life and are expensive. You are building disposable cars.
3. Batteries take time to charge. Go for a drive across the country and you might end up waiting long times.
4. Batteries have issues in temperature extremes both hot and cold.
5. Batteries are not green, regenerative, sustainable, clean and it is questionable if all of this environmental push is even rooted in reality. Batteries use rare earth or heavy metals, are energy intense and dirty to manufacture, and they lose about 15-20% of the power when being charged (they resist) taking away much of that “efficiency” argument. That doesn’t even take into consideration where many of the materials in a battery come from and how slave, child, and unsafe labor conditions, or environmentally disastrous these minerals/elements are mined for.
