That is going to be an expensive habit in the future once time-variable pricing is the standard, which I think is inevitable. Charging your car at 6PM is going to be super expensive compared to 3 AM or 1 PM.
Also note you'll still have fast-chargers, you don't always need to charge immediately at full capacity at home, just as you wouldn't always top up on gas after every drive.
Just a note for any UK readers that this is coming in sooner than you think. There are already proposals on the Ofgem[1] site to force mandatory half-hourly meter reads that mean energy companies can offer pricing that more closely matches demand.
don't want to be part of that? run your house off your EV and charge it back up at night. my house takes about 6KWh a day, so I could run it for almost a week from my car even if I didn't charge it.
