> cars are more fuel efficient

This is true when comparing the same class of car to previous models, but is it still true overall when we consider the shift to larger vehicles? The Toyota Camry from 1994 is still more efficient than the current 2024 top selling Ford F150.

Jevons paradox is worth considering when reading these stories of increased renewable energy generation and falling prices.

Yes! Automobile fuel efficiency is now probably the classical example of Jevon's paradox: some cars are more fuel-efficient; and (therefore?) we in the United States are driving 35% more miles each year in 2024 (3.3e12) than in 1994 (2.4e12).

Which makes our total gasoline consumption about the same as or higher than the 1990s, within 10% or so:
