Re: the "grid storage" issue.

1. The electrical supply is not 100% stable. There are substantial voltage fluctuations in any 24 hour period. Line stabilizers are needed to shield sensitive equipment from voltage sags and spikes.

2. Demand is predictable. In that same 24 hour period, people get up, shower, turn up the heat, and go to work. Temperature forecasts are a good predictor of heating and cooling load. Wind forecasts tell you how your wind turbines will perform, overcast conditions affect solar arrays, and power system management tracks all available factors. Flexible generation capacity can be brought online on a daily schedule. Natural gas turbines can be brought online in minutes. Hydro turbines are right behind, limited only by how fast they can open the penstock without blowing the power house apart.

3. While household electrical demand is constant within predictable limits, major industrial users have to coordinate with their power suppliers before they start up major equipment like steel induction furnaces. Except in emergency, they will also coordinate shutdown.

4. The only real time online storage is inertial. Increasing load on a generator will cause it to slow down, but there is spinning mass, sometimes substantial, that resists slowing. Utilities generally keep the resulting voltage sag within 5%. Anything over 10% is a brownout. 1% to 2% is negligible. Let's hear it for angular momentum. Likewise, a generator can be spun up and ready, but uses very little power until it actually generates some.

Oh, and you notice I don't use the 'G' word, which is nonsense noise.

Building roads would become cost prohibited for cities. Then what happens when a pot hole shuts down 5 o'clock rush hour with everyone stranded with dead batteries?

If building a grid above ground is challenging, imagine putting it in a road.

So let’s do nothing. Don’t worry, other countries will figure it out, just like they have health care, and get it done. This will not be America’s century, we’ll be too busy arguing about it and modifying our pickup’s chips so we can roll coal.

A pothole, just like a dead coil wouldn't be relevant. The EV would still have batteries, it's just that the range wouldn't need to be that much...100 miles on just battery would be plenty.
I'm sure Interstates would be the first modification, then highways, smaller roads, etc.
Sweden is already working on electric roads, but to me I think of slot cars we had in the 60s. Induction, although not extremely efficient seems like even small charging mile after mile would add up as you drive.
I'm just thinking...

I will say it again, electric cars don't make sense right now. Ditch the concept all together. Turn the focus to residential and commercial solar capture with battery storage. Scale to the load as needed. Alleviate the stress to the grid, then you don't have to build it out in the future.

It makes no sense to force a square peg into a round hole. Trying to electrify transportation requires downtime to charge at specific locations. Industry is not going to slow down for charging when there are super fast and convenient alternatives available and proven. It defies all economic laws, it's not sustainable in the long run.

Which brings us to the elephant in the room...batteries. They're not there yet. They need to store about 10x more energy before it makes economic sense in a car. I'm sure we'll get there, and then accommodate the tech.
