Thaler and Sunstein in their book Nudge, The Final Edition, suggest: “If the goal is to make the environment cleaner, a simple idea is to make the green option the easy option”. My takeaway: When encouraging folks to choose a zero-CO2 vehicle, the recommended choice should simply be better than the alternatives.
My first two Hydrogen Fuel News articles (at https://tinyurl.com/33syb2dz and https://tinyurl.com/2d7crwkh) recommend that Ford should change course immediately to hit this goal. The driving range of its new battery-electric Lightning pickup will be anemic, especially when towing a trailer. Ford should convert it to hydrogen-electric and support it with a country-wide “starter network” of fuel stations. Those stations would produce their own hydrogen on the spot, from solar electricity and water – no tanker trucks or pipelines need apply. A hydrogen-powered “LightningH” will have a thousand-mile range using its 580 kWh of stored energy — 500 miles even when towing a travel trailer. The result will be a truck that can do its job better than any other choice. The only Nudge required will be built-in: word of mouth from owners enthused about its superior power, range and whisper-quietness. It’s easy to imagine 50 million clean and green H-trucks on the road by 2035, given the 60 million fossil-fueled pickups out there now (with ten-year average lifespans). The LightningH (and H-trucks from other manufacturers) should own the market well before 2030.
But wait, there’s more! 
About ten million of us own RV’s, happily navigating them through the North American vistas. Trailers and motorhomes must also have zero-CO2 propulsion within a decade or so. What if we follow the “Nudge Rule” and develop RVs that are better in every way than the current models?
We can! Let’s have a little fun with the LightningH chassis:
