Of course, if we can just wish businesses into making climate-friendly choices (like moving fleets to EV instead of ICE, per your example), then we can just wish Shell into getting out of oil and gas altogether. And the corollary is that if we can't wish Shell into getting out of oil and gas altogether, then we can't wish other businesses into making climate-friendly choices, so we're left with politics: penalizing (instead of incentivizing) fossil fuel consumption (including border adjustments so we don't just export our consumption of fossil fuels) and/or national programs to shift the grid to renewables and electrify fossil fuel applications.
