Gasoline is not in itself an incendiary bomb, it has a specific meaning:

— it burns for a long time - it resists suppression

If you want gasoline to meet the definition you have to make napalm out of it.

Sure. When was the last time you had to store gasoline in your residence though? Do you have to manage fuel storage on your person to power devices? Does Amazon have to send you a box with petrol in it when you order a laptop? There is infrastructure around petrol and designated places to contain it and dispense it. We don't have that yet with battery power. Most people just ignore the X with the trash can on the device and dump batteries in the garbage. I don't know about you, but people where I live have to go out of their way to find a place to drop off their old batteries responsibly, and I think I am the only person I know who does.

Pretty much everybody stores a massive amount of gasoline energy on their property every day, as gas in the tank in their vehicle.

And disposal of car batteries will never be an issue. Even the smallest and most degraded of Nissan Leaf batteries is worth $2000 or so.

You are not engaging with my point and are trying to work around it. You know that you are doing that and I know that you are doing that.
