We have been over and over and over this with you, specifically, for several months now, and you don't seem willing to receive the information. Because of several kinds of price changes and code changes, the situation now is WAY different. It really doesn't cost any more at all to just do the wall connector now than it would be to do an outlet and mobile charging cord now. They are the same out of pocket cost for someone ordering now. (Or actually, it seems just barely cheaper outright to do the wall connector.)
So this doesn't have to do with whether it rains in your garage or anything else. It's simply not more expensive to do the wall connector for new buyers, so that is why the sensible advice is different now than what you are telling people.
The reason I don't respond is that I don't comb through the article and its subsequent comments to see what people have had to say. Yes, I'm probably wrong, comparing a ten-dollar outlet with a few-hundred-dollar wall connector, but if it really is nearly the same outlay, then of course one should buy the wall connector. But they should also realize that other options exist which actually are more useful and less expensive. Oh, I mean they're the "same ... cost". But not for me.
Basically, I DO NOT BELIEVE that it costs the same, and I doubt you have that proof. It only costs the same "for new buyers" because they cannot learn to do any of the work themselves and must hire some overpriced electrician. I've even had my daughter do part of the wiring for her outlet. It's not rocket science.
If it were me, and it is, I'd check on the prices, for it seems impossible that an outlet I can install ($30) would cost the same as the connector ($400 not counting installation). Both of my cars came with the charging cable, so my
only outlay is my outlet. My garage was not yet sheet rocked, so running my 6-3 w/ground was a matter of buying the wire and pushing it over the ceiling joists. The outlet just screwed to a stud. I have never handed over such a simple job to some dude who has an electrician's license and charges $400 an hour, which immediately means I pay less because I have the intelligence to know what I'm doing. THIS is why it's cheaper for me to install an outlet over buying a wall connector:: I do my own work.
All thirty minutes of it.
I feel sorry for the masses who are unable to do this simple job, who pay extra for simple work, and who are unwilling or unable to gain the knowledge to do it themselves. I wish, deep inside me, that others could figure this out. It's cheaper to learn something that you can use over and over again in the future than to hire someone to do it for you every time you come upon another SIMPLE job, of any kind. It's cheaper to vacuum your own carpet than to hire a maid. My county says the I can do my own work at my own house at minimum expense, but an electrician must do the work if I don't, and charge me a bundle. That's not too smart. I've wired a couple 220 volt outlets at no cost for friends who only wanted to charge their cars in their garage, and no, we didn't blow a $400 wad on buying a wall connector.
As to charging both cars in succession, I can do that, too, by using my phone app to tell them both when to start and when to stop. Again, it's not rocket science.
