Obviously a city car doesn't work for you, since you take occasional road trips up the 395.
But it could work for people like sdifox's more significant other.
There is no infrastructure around hydrogen fuel cells, so that's not an option. If you must buy a used car before 2030, you can get some kind of hybrid that fits your needs and budget.
I prefer buying lightly used cars, and it'll be years until a BEV makes sense for me. Tesla is the bulk of Elon's net worth, so I will never consider one, even used. Although I believe the U.S. and EU should protect their auto industry against unfair competition (Chinese brands), I also think that long-term, the best thing for consumers wallets is if the Chinese manufacturers are tightly regulated and enter our markets fairly. New autos have gotten way too expensive over the past decade, and Chinese BEVs are the best hope for competitive forces.
Although I'd like nothing more than Elon's comeuppance, you're looking at SpaceX the wrong way. It's more like if not for SpaceX, where would NASA be today and over the next ten years? SpaceX is literally "too big to fail now" for U.S. space interests. There is simply no viable plan B besides SpaceX's continued success, further enriching Musk's net worth.
Tens (hundreds?) of billions of dollars have been spent globally on BEV development the past couple decades. The idea of a "crash program" sounds cute, but R&D hasn't been the limiting factor thus far. Battery tech has gotten much cheaper over 15 years, but there just hasn't been a breakthrough that would enable even cheaper/smaller packs. There's significant hope that solid-state batteries will eventually get there.
