What the car is capable of verses what you can actually find to plug into are often two different things! Take even the i3, IF you have access to a CCS unit, 30-minutes to 80% from nearly empty, and about double that to full. But, you don't have one at home, and on the entire east coast of the USA, there's less than 25 or so and none within range of my car!
Most of the public level 2 EVSE's out there are running off 208vac power, and if they are 30A, that's only 6.2Kw/hr. Throw your Tesla on it which may need 85Kw to recharge and see how long it takes! It's irrelevant in many cases how fast you CAN charge, it's how big the device you plug into is.
Then, I still contend that the average home does NOT have 80A free on their power panel unless it was specifically installed with that intent for an EV. A more typical 30-40A unit is a stretch for some.
You can look at the ideal situation, but few people live in that ideal world. There isn't a Tesla superstation in my entire state, and if I did have one, just to use it, I'd lose about 1/3 or more of my available range since I don't generally travel that direction! There are VERY few CHademo DC fast chargers east of CA, either. When you look at the entire country, and all of the very large companies that have agreed to go with CCS and J1772, the prospect of better coverage looks much brighter if you open your eyes. It will take time. Level 2 units are fairly easy to install. Running power (if it is available, often not) to a CCS unit is a major endeavor, and the unit could be 50x more expensive to buy than an EVSE. Without incentives, there has to be a fairly big market to justify the expense with any expectation of recovering your costs...they aren't putting these things in for goodwill unless coerced - there has to be a market case for it. You can put in a gas station and expect nearly 100% of the passing vehicles could stop and utilize it. How many EV's are there out there, and then compare the time required to fulfill their needs?
Some people buy things on a whim without research...hey, a car is a car, it will perform like any other car I've owned! BS...EVs are a different animal. How much responsibility is it of the seller to educate you? They should have the answers if you ask questions, but hey, buyer beware! My i3 is meeting all of my expectations. Do I wish it may do a few other things? Certainly, but I did my research and decided the benefits outweighed the deficiencies. As to range...how many people get the EPA rated performance on the car they own? Some, IF their driving conditions are similar. How often does that happen? Based on the way the EPA measures things (you can argue whether it's right or not), the i3 BEV gets 124MPGe...do you know any other car that can go 124 miles on a gallon of gas equivalent? How you drive and the weather conditions and where you drive all affect an ICE as well as an EV. Cold starts, short trips in the winter, my ICE might get 1/3-less MPG than in the summer. Even on a long trip, winter to summer (partly because of the ethanol, but where I live, we get that all year), I'll typically see around a 15% degradation.
Things will only get better, but I'm not disappointed in what I have...my i3 does what I wanted and expected it to do.
