"> The grid doesn't have the capacity to do that for a fleet of 32m cars
Based on what calculation ? My commute is (was) about the average length for the UK, and an overnight charge could be done for under a kilowatt. If the power distribution network can cope with everyone's household appliance peak use (around suppertime), it certainly won't be broken by a kilowatt while you sleep"

Let's see...
1 kw x 32,000,000 = 32,000 MW
Or about 30 to 40 nuclear reactors at maximum.
I'd start building them now.
