Electrifying the transportation sector is generally seen as a 15-25% increase in grid demand.
These are vehicles which most can schedule their charging to take advantage of low electricity prices and therefore low demand.
The uprating needed is quite insignificant.

Quote on that? A developed country like the US has problems even now, see California (with the yearly fires there) or Texas. And how do you solve the "last-mile" connections without regularly starting fires everywhere? (on account of all those higher-voltage thingies being closer to residential units).
