The point is that maybe most(some?) people don't need DC charging at all. I've owned our VW e-Up for 3 years now, drive it literally every day, and I never needed to fast charge it because I've not once taken it on a trip longer than its battery range. I just never had a need. In fact I'm just charging it from a normal domestic socket at a meagre 2kW once a week and that's absolutely enough. Obviously it won't work for everyone, but I bet it would work for a whole range of people - some of my friends have definitely never driven more than 100 miles in a day in their cars and they lug around 50 litres of petrol in their tanks "just in case".
