Would you like to go visit Italy? Of course, who wouldn't. But understand that the CO2 burden of a return flight from India to Rome is somewhere around 2-3x what the planet can sustain, per person, per year, and that for all the hype, carbon-neutral aviation fuel is so far nothing more than a dream. And you're telling me that you've seen all the wonders of the world within a short-haul flight from home?

So once in a lifetime? Sure. But if people do this routinely, the planet pays, which means someone somewhere pays. Our environmental debt is like a maxed-out bank loan at this point. And those people will paying the price will almost all be poor. Tell me what's more likely: a future where the poor get to fly to Italy every year, or a future where the rich and not-quite-rich do that until we really do run out of room on climate.

In my city we're using electric two-wheelers increasingly. It requires good road design, low speed limits (20mph or even 25kph), high standard of driver training, and well-designed vehicles with good brakes etc. With those things in place, it's possible to operate them safely, and on 1/20th the energy budget of full-sized EVs. 20mph doesn't sound like much, but in a big city it's fast enough to cover a lot of ground, and do so in relative safety.
