Fact from Teslarati.com11 Sep 2020 08:48
In a brief interview with Teslarati, Shigaev, whose company is developing batteries that use aqueous (water-based) electrolytes, noted that while supercapacitors will likely not be involved in Tesla’s million-mile battery project, there are already a lot of local tasks in an electric vehicle that could benefit from the use of supercapacitors. Among these is smart air suspension, a feature that is currently used in the Model S and X and is expected for upcoming vehicles like the Cybertruck. But beyond this, the Geyser Batteries CEO mentioned that supercapacitors could also be utilized as a superior alternative to the 12V battery that Tesla uses for its vehicles today.
“The more stuff gets electrified, the more power you need to perform tasks. The most classical thing (that could benefit from supercapacitors) and the number one item for Tesla is the 12V battery. Supercapacitors can handle this task. If you have a high energy battery onboard, then this secondary circuit could be powered by a supercapacitor that is very efficient. It will even have an extremely long life cycle. Supercapacitors are lighter too, saving weight. And they tend to be smaller than a lead-acid battery,” Shigaev said.

Even in case supercapacitors will not be mentioned on the 20th (supercapacitor day), according above there will be a massive amount of supercaps in the each near future vehicle. From small to big.
Imagine which scale this is in combination with lorawan, energy harvesting and so on...
Even with loosing the Maxell case (which I do not not believe) the future for cap-xx is far more bright than the current shareprice ;-)
