One of the prime rules of storytelling is that the hero has to have a flaw.
Superman is super. He can’t lose. That’s why the writers introduced Kryptonite. Captain America is a super-soldier, but is still mortal. Thor is a god, but can lose his hammer and his powers.
The problem with Superhero movies is that they all got so much power they became invincible, and boring.
Good, classic storytelling beats VFX 10/10.
1000 charge cycles. If you charge twice a week, that’s 500 weeks or a little less than 10 years. There’s no mention of degradation over time.
But back-of-the-napkin, it means for this to be cost-effective, they may want to come up with some sort of replaceable or battery swap system. Not sure anyone will want to buy a vehicle that needs a massive battery retrofit every 8-10 years.
