The oil major projected that oil demand would remain at 85 million bpd in 2050 even if every new car sold in 2035 is an electric vehicle. That's roughly the same level of demand as in 2010.
Taking it as generic fossil fuels seems silly because coal usage is quickly disappearing everywhere. Coal is not cost competitive vs solar.
(most likely it's because personal transportation is < 30% of total energy use and energy use is probably going to keep going up)
The problem is small (ish) batteries. Like those in cars. Which is why it's very, very important to start phasing out large scale automobile transportation. We've had electric trains for decades and not only are they orders of magnitude more efficient per passenger, they also don't require batteries.
