I agree we're probably past peak oil, but i think i disagree a bit on cities becoming more dense - i think video conferencing and remote work put much less impotus on people to congregate like we once did, and yes that likely will mean more strain on the roads, but i also think the electric cars will be more like a spreading out of electric storage and transmission than 100% used for transportation. (Again due to increasing popularity of remote work) having a store of electricity will be posh and help guard with the rolling brownouts due to climate change and terrorism interrupting the grid.
