Really? Electronic ignition and fuel injection alone are advantageous enough, not to mention the ability of at least one Rotax engine to use true automotive gas (gasohol).

As the article points out, the writing was on the wall for leaded fuel decades ago. The GA industry killed itself by dragging ass on eliminating the need for it, abetted by the burdensome FAA certification process for any aviation advancements.

It may be too late to save GA. BasicMed was a big help, and the increased pace of STC approval has been a boon. But with the FAA derelict in its duty to protect airports (see the sellout of Santa Monica as an example) and corrupt local governments eager to destroy our public airports and sell their land to developers... the future looks grim indeed. Just as electric training aircraft, unleaded fuel, and less-polluting and more-efficient engines render the anti-aviation cabal's excuses moot.
