The horse is way out of the barn on this one. Automakers worldwide are already committed to all-electric for cars and light trucks by the mid-2030s, and will be at 50/50 for heavier chassis by then - anything that operates short-haul will be electric, long-range will probably stay diesel for a while longer absent an order-of-magnitude improvement in weight-to-power ratio or charging time for batteries.
And then when the grid breaks down, everyone is forced into mass transit.
