(As another data point, I see Teslas regularly parked in my London neighbourhood outside homes that do not have any off-street parking/charging. So at least some EV owners get by without any home charging at all)

Again, it seems like selection bias, in that those high-mileage drivers who can use electric do, and those that can't buy diesel. Presumably there is a cohort of diesel drivers who would switch to electric if they offered sufficient range or faster charging, especially as diesels outnumber electrics ~2.5:1 in the UK [2].

There's still a significant price gap between comparable diesels and electrics.
Norway's experience (60%+ market share for electric vehicles) suggests that if the price is comparable, and charging is convenient enough, the majority of buyers will choose electric.
