If the standard of living goes up fast enough, developing nations can leapfrog past car-dependency and save their battery capacity for highly battery-efficient micromobility vehicles like ebikes, etrikes, and escooters.

An ebike equipped with a 1KWh battery can go 30 to 50 miles on a charge with throttle alone, while a Tesla Model 3 with 70KWh of battery capacity can go 300 to 375 miles on a charge. That's 70 times as much lithium for only ~8x as much distance, which means that hauling a whole car around with you is about ten times less efficient than an ebike.

I don't think that would be likely given that human sex development is decided by the presence or absence of the SRY gene. Without that gene activating, you develop female. So without a Y chromosome, the SRY would have to find somewhere else to live.

  1. In the Netherlands, there are plenty of old people who walk or ride bikes. There is even a type of bicycle that is stereotypically for grandmas- "omafiets".

  2. If you're not fit, you can become fit by walking or riding a bike.

  3. There are plenty of disabilities that prevent you from driving, and plenty of motion-based disabilities that let you get around perfectly well with a wheelchair or an adaptive cycle.

  4. They make child seats for bicycles so you can bring along kids who are too young to ride their own bikes.

  5. I'd expect not because there are presumably a lot of good restaurants within walking distance, however, assuming there is a grocery store within walking distance (because "walkable areas" implies that everyday necessities like grocery stores are within walking distance), you can also transport groceries on foot or by bike.

This. Swapping out batteries is possible by default on the vast majority of ebikes, because you take the battery out to charge it. But car batteries are just too big to take out easily.
