Can you please get me a driveway? And while you are at it, thousands of people that live in my neighbourhood would like one as well. And make it two driveways for the households with two cars.

Well, I addressed that yes there is an infrastructure issue for street parked EVs right now - so yes, probably not the best time to buy an EV if you don't have off-street parking of some kind.  But, about 50% of people -do-, so they should have much less of an issue.  Besides, charging at 2am would still be perfectly possible for on-street parking: delayed start is a thing. 

And, why would you need two driveways for two cars?  They don't need to be charged at the same time.  You don't need to fill your petrol cars at the same time. 

MadScientist:
This idea that future EV will be charged at home , is entirely misplaced , firstly increasingly powerful chargers will not be available at home and range and recharge tine limits , will limit the useability of home charging

Residents of apartments etc or those without “ driveways “ will simply use high powered fast charging stations which will replace filling stations.

Nobody needs a driveway to use a  EV.

A 7.2kW home charger (230V, 32A - standard 'level 2' charger)  is enough to charge at around 30 miles of range per hour.  So parked from 6pm to 6am, 12 hours, it adds 360 miles of range, if you use every minute of that to charge and have a battery big enough to store that all...

In what world are you doing 360 miles - or 131000 miles - per year?  There's absolutely no need for a home charger to top up more than your commute plus a bit extra. I do about 50 miles per day when commuting and a 2.3kW (230V, 10A) granny charger would be enough in a 6 hour period.  I only have a PHEV, so about half of that is electric and the other half is petrol, so my car is done in 3 hours.  Fits nicely in the off peak period so I haven't bothered increasing the charging power.

If anything one of the huge benefits to owning an EV is it frees you from the need to charge up in public, it charges just like your phone does... overnight, while you sleep, you need to do nothing but plug it in.

Yes.
