I think you are incorrect. Depending on a plug within your house is not a solution. That is avoiding the problem. Solution* is U.S. government rolling out standardized electrical socket plug for vehicles and investing in infrastructure to make it cheap enough to be installed virtually everywhere. After that getting commission together and drafting set of standards for wireless charging (this is decades away, but it needs to be common if we are to see electrical cars supplant fossil fuel vehicles universally.)
Personally, I think the solution is for electric cars to have enough range that you don't need to plug them when away from home on routine trips, and for charging to be fast enough and available enough from dedicated stations that you can still do road trips.
Even if every parking space out there has a charger, I don't want to plug in every time I park my car. I want my car to go hundreds of miles in between charges so I don't have to care. That's not yet practical unless you spend serious money, but anything else seems like a workaround.
* Or one of them solutions.
