An idling gas engine may be annoyingly loud, but that's the price you pay for having WAY less torque available at a standstill.

Sure, but even then there are plenty of cases where a solar panel doesn't make much sense either. If you're cutting down a tree in the woods, would you rather grab your gas-powered chainsaw out of your truck and cut down the tree, or grab your solar-powered chainsaw out of your truck, spend minutes setting up solar panels to pick up the small amount of sunlight which makes it to the forest floor, and then cut down the tree?

The point is there will always be a market for ICEs until there are batteries with competitive energy density to gasoline. You don't see solar- or battery-powered trains or construction/mining equipment because these things need huge amounts of energy to work, energy which can be easily stored in a fairly small fuel tank (which can be quickly topped off when necessary).

Absolutely, just like there's some things a horse can do that a car just can't.

I don't plan on buying a horse or needing to do those things, and I don't think the vast majority do either.

The end result is that there will still be ICEs in niche applications, but those who know how to operate them and the supply chains that currently make them cheap and dominant will slowly die off.
