Building a carless society will take time but we need to get rid of gas right now. The difference of emission for the use and manufacturing of an EV is absolutely not close to the cost of use and manufacturing of an ice vehicle PLUS literally burning gallons just to move it.
Oil companies, their assets and the assets of the barons who own them should be violently seized and used to offset the cost of what they created. Until that happens, we will have to suffer a bit or we will be stuck suffering so much more probably sooner than we think.
