"How many days per year is it not too hot or not too cold?" Perhaps 300. The issue there was to not charge electric cars at times of highest demand for electricity from the grid. We can either live with what we've got, or increase capacity, or find other methods.
"What do you think is going to happen when more electric cars go on the road?"
People will drive them and use energy much as people nowadays or 30 years ago have driven cars and used energy.
You seem to think that the electrical grid is, or will be, less reliable than gasoline or less good to use than gasoline is good to use. That may be true for some times and places, but it doesn't have to be.
For now, the electrical grid in the U.S. sometimes has trouble keeping up with demand. For the past 50 years, burning gasoline has been polluting the air. Each mode of energy has its problems.
Electricity is relatively flexible in that there are a variety of ways it might be generated. Gasoline used to be more convenient for long distance travel by car, but that advantage of gasoline is slipping away as electric car ranges are getting longer.
There didn't used to be a big infrastructure for gasoline-powered cars. Such a thing would have been hard to imagine existing, before it got started. And yet people did build the whole cumbersome thing, along with the attendant pollutions and wasteful uses of energy; and including the rubber-tire industry and hard smooth roads and parking lots taking up land. An infrastructure for electric cars is no worse, and will probably be better, but only if people decide they want it enough to try it (basically the same situation as that regarding gasoline cars when they were starting). It _could_ possibly be squashed if there were a big enough propaganda campaign (most likely by the oil industry) against it, but I think the cat is out of the bag by now, such that enough people have seen enough undeniable evidence that electric cars work.
Mass t***sit is another good idea; but, unlike mass t***sit, electric cars preserve, or can preserve in the future, the convenience and individual independence and privacy that gasoline cars have given us.
Besides all that, even today we have plug-in hybrid cars, like mine. I can use the electric grid or the gasoline grid, either one, at will. So far my electric-only range is 50 miles, which is just barely enough for "necessities" (in my current manner of living). In the future I'll very likely have a car with electric-only range up to a hundred or two hundred miles. Battery technology is getting better and less expensive.
I'm sure there's some pollution associated with batteries, but I have no reason to think it will be any worse than the pollution associated with gasoline. I expect a lot less pollution and a lot less complication, with electric cars, than with the gasoline cars.
Personal cars (together with the supporting infrastructure for personal cars, and the city layouts and lifestyle) are mostly a luxury (there are more economical ways that all of it could have been done). I could (and have in the past) live without a personal car. With my current plug-in hybrid car, I've achieved this level of luxury while partially reducing its harmful effects on the environment (with more reduction, of harm, to come with future developments).
I cannot (not easily) do it all myself (I suspect that some of my electricity is coming from dirty coal burning), but I can do my part and v**e for people who will do their part.
