Which also means that a much cheaper 200 mile range vehicle is here. Lighter EVs are more efficient, less road wear, tire wear, less vehicle wear.

  Everything points to solid-state batteries being quite expensive and prioritized in higher end cars, think iX3/GLB/GLC/EX60, where people want more range and care less about weight (these cars get 100+ kWh batteries today). It will take time for these batteries to trickle down to lower range cars, I think.

    Initially yes. Longer term light vehicles will enable light vehicles which means low cost.

    And if you can charge faster, you can use an even smaller battery.
    If we could automatically plugin every time we parked, our battery could be sized down to just large enough for the distance of the max trip times margin.

There are now close to 10 major efforts to bring solid state batteries to the mass market ASAP. Front and center is the stated goal of proving all of these new types to a cold weather standard, including all saftey and environmental considerations. The automotive sector will be dropping fossil fuels fast, fuel shocks will only hasten this. Quite sure I wont be buying any new ICE engine powered car, ever.

  That is opposite of what is actually happening. IDK why there is pullback from EVs tho. Was thinking perhaps Cybertruck embellished this as a symbol of "excess" or something (despite being pretty practical and somewhat affordable work truck, contrary to popular belief).
  It could be overall US policy. Renewables decrease dependency on oil, which decreases demand petrodollar (which is about 1% of US GDP so not sure if it's worth the squeeze for US), while also growing China's exports.
  Notable mention is China is doubling down on low altitude economy (eVTOL and drone delivery) which pretty much depend on solid state batteries.

    Trump cancelled a tax rebate that instantly made every EV 30% more expensive in the US.

    But why did he done it? Rest of the world did the same - in NZ incentives got pulled and we are even taxed additionally per km now - same as 3 ton diesels, Europe pulled incentives and lowered emission guidelines...
    All while interest rates are high and large upfront investments are harder for people.

    Trump administration also cancelled funds for charging network buildouts, has fought solar and wind energy construction, put in high and erratic tariffs on key technologies related to EV construction. There is also a concerted effort by this administration to push the narrative that EVs are a failed folly and there are well funded astroturf campaigns pushing the same message. Americans are told daily that EVs are unreliable, the batteries die quickly, and you can never find a charger. Meanwhile car makers are cancelling plans to bring out EVs. It makes for a harsh climate for EVs in the US. EVs are still selling but its an uphill climb and the numbers show it.
