That’s an awfully uncharitable projection.
The lawn business people I know would love to adopt full electric fleets of gear. They aren’t sending their teams out with gas engines because it’s a “fantasy escape world”. They do it because gas engines are currently the only reasonable way to keep the crews running all day without spending thousands of dollars on batteries over and over again.
Current battery tech is hit or miss. The packs should be protected from over-discharge and last for hundreds of cycles, but in practice they got a lot of early failures. They also need extra packs to rotate while others are charging. At $100-200 per battery, they might be spending $1000 on batteries to operate a machine for a season, which would have bought them two gas powered machines and gas to operate them.
There’s also the issue of charging throughout the day. Getting a reliable charging setup that works on a truck inverter and getting crews to perfectly manage batteries throughout the day, including spares, is significantly harder than just filling up a gas tank.
Projecting all of this on to “fantasy escape world” is silly.
