Do BEVs still use a 12V lead acid battery?

Yes, my Model Y has a "traditional" 12v lead acid battery. Granted its a small battery as it doesn't have to run any heavy loads (starter motor). Furthermore, it's my understanding that newer Tesla vehicles are being delivered with 12v gel batteries instead of the the lead acid design.

That's a bit silly. What's it used for? Couldn't they just use a step down switching power supply that draws current from the main battery?
