> Self driving cars might have set destinations that are cheaper to visit,

I think you mean set destinations based on an auction of what business paid most for your visit, based on your demographics & ride history.

Ah good, more terrible things to look forward to.

All the while creating more CO2

most (all?) self driving companies are electric. Cruise, Waymo, Tesla

And how is that electricity generated in most of the US/world?

And how those cars were built? Electric cars generate more tons of CO2 to make than conventional combustion ones. But it's expected to pay off as long as the electricity is generated cleanly.
