They are not actually that exceptional anymore. At best they are marginally better.
Tesla new architecture of structural cells in a pack connected to massive castings is far better then Toyota EV have.

I really don't think that will be the cast.
> Imagine we hit "peak" Li-ion around 2030, producing 75 tWh annually. (Amazing, right?)
> From their website: Storage is 30% lighter, 7% smaller, and 17% less expensive than Lithium-ion battery per kWh.
By the time this technology is even remotely feasible. Li-Air, Li-Sulfer batteries and a whole bunch of other potential chemistries could be ready. All these more advanced chemistries can beat these advantages without issue.
Li-Sulfer battery could be 2-4x as dense ad current LiIon far smaller and far cheaper.
Even current High Nickel Cathode-Silicon Anode that will roll into the market will beat the numbers advertised by the company.
Why would anybody go refuel with solid hydrogen when you can have better range then Tesla Model S with a battery small battery pack you can put in your trunk and a tiny powerful EV motor?
A car based on the technology is simply worst along every single dimension.
