Once the atmospheric CO2 levels rise high enough, this will be sold with an included CO2 scrubber. Then you can mow your lawn without getting symptoms of CO2 poisoning. Like in the good old times in the 2020s!
that's why we engineered the lawn mower to run on only the dirtiest fuel available, and a sufficiently inefficient engine that it consumed 50 liters to mow the average lawn!
