I hear you but trust me, it isn't a thing. You think it is but when your car sleeps at the gas station every night and you're waking up with a full charge, it isn't a problem. But I won't blame you if you come back to me and insist that it is because before I owned the car I would have said the same thing.
If you guys want a fun anecdote (I know you don't but I'm going to tell you anyhow), I JUST yesterday had a 240v outlet installed at my house and only did it because I had an electrician over for other stuff. What's that mean in practical terms? Well, for the last 2 years of Tesla ownership I've been charging at a rate of 3.7 miles of range per hour at home off a 110v outlet. That means that for every hour my car was plugged in it would get 3.7 miles added back onto it's range.
And it still wasn't a problem unless we had just returned from a road trip and I had to head out the next morning some place far to meet with a client but that was such a rare occurrence as to not be a realistic problem. Now the car charges at a rate of 30 miles an hour and if you get the high power charger they charge at 60 miles an hour.
As the batteries continue to get larger and more efficient though, you're going to see the charge speeds increase as well. A larger capacity battery can charge at a faster speed and a more efficient battery doesn't necessarily charge at a faster speed but because it's more efficient it's getting proportionally more range than the less efficient setup.
Another anecdote... The 60kwh Model S's supercharge at a slower rate than the other cars. The reason is because their smaller battery can only charge at a certain speed safely. So when the 3 came out the concern was that it's smaller battery was going to result in the superchargers getting choked with cars. But now that the cars are trickling out what people are finding out is that because the 3 is smaller and lighter, it's much more efficient and so it's charging rate by a factor of how much mileage it can add over a period of time is actually the same, if not a little better than the higher capacity S's.
