Stuff to consider - 

There are far more houses able to charge an EV than there are batteries for this many Household EV combinations. That clearly does not mean everyone can charge one at home or that there are not millions who presently can not do so.  It means that the grid is not the real bottleneck. Battery supply is.  Ask any car maker trying to build an EV. 
So let’s talk about peak power problems and the solution. 
Our solution might be batteries. 
The average Tesla or EV has enough kWh to power the average house for 3-5 days. (75 kWh)


The problem is, as clearly illustrated, power companies have an energy storage problem when peak demand is down but the wind is blowing or sun is shining.  In Australia they built giant batteries centrally to solve this problem. But why not distribute the solution and minimize the single failure points?

So imagine your car becomes a VPP. There it is again.  Virtual Power Plant. Let me explain a bit.   
You charge your car fully between midnight and 6am (see Gladstone’s chart of prices for why this cost effective).  When you are not driving your car you use it to run your home anytime the power cost is not at its lowest (or when most expensive).  If you have extra power in your car you might even sell it back at a profit. With 30 or so of the 300 mile range being used daily on average you have a lot of capacity left to balance the grid, reduce your own electricity cost and still drive your car.   Your car will be able to sell its excess power even while parked at work in the city where power might be worth even more and hold back enough power to get you home and run your house until midnight - the cheap charge time. 
While the car currently does not support bi-directional charging it is certainly in the future. Lucid is already planning to do this. Tesla already has the brokerage software for the load balancing and marketing of your battery power. They do this in Australia.  

Disruptive tech is not high tech all the time.  it is often common advances used by low end but high achieving hobbyists. The path in this case is pretty simple and obvious. Use batteries to load balance, add stability and reduce costs. The batteries in these cars will already last several times the life of the chassis.  The vast numbers of batteries required ensures that this will be far more of a bottleneck than the current power grid. As mentioned the current grid is way ahead of our battery supply.  As more EVs come on line, and if they are load balanced, we will see far fewer brown outs and power shortages during peak times. Like the Borg or internet packets your have more of a collective preventing failures.  As a bonus you have a giant battery backup for your house and perishables that could last for days. Imagine how this would impact the developing world in 40-50 years. Can you see a different future?

These are simple steps which are not drastic and fairly logical.  It’s an engineering thing not a Tesla or even an EV thing.  No need to be defensive.  It pretty easy to see how this works once you understand the roll of batteries and their underutilization in the current EV scheme.  This is how we will adopt EVs, integrate solar and wind and ultimately drive the cost of electricity way down while making it safely available to more people - cleaner.  

While clearly not every grid or homeowner can own and charge an EV today the actual number TODAY who can is many multiples greater than the supply of batteries today.  If you are looking for where to invest ... I suggest batteries 🔋of all types.  
One thing I’m not concerned about is the ability of the grid to keep up in the long term - perhaps now you see why.
