Sadly I agree with your comment. As a Tesla owner it's clear that GM and the others just don't get it. There's a reason that the Cadillac ELR failed miserably and that Tesla is eating everyone else's lunch when it comes to EVs. When gas got cheap, sales of the other EVs fell significantly. Tesla still can't keep up with demand yet they do basically zero advertising. They've worked hard to address all of the issues people have with EVs, including range, charging and performance. The people who complain about how long it takes to charge a Tesla don't have any experience with it.
The only reason that the J1772 standard can handle 20KW is because Tesla fought tooth and nail for it. GM and the others would have been happy with a 3.3KW limit. They also should have adopted something like Tesla's standard for fast DC charging rather than the Frankenstein SAE combo plug or ChaDeMo.
When it comes to battery technology, Tesla is years ahead. Their batteries are much higher capacity and much cheaper than what GM is using.. Despite being manufactured by Panasonic, Tesla owns much of the IP in their batteries and has numerous patents on them. Once their gigafactory comes online, Tesla's cost for batteries will drop by at least 30%. Their cost are already the lowest in the industry in terms of $$$/KWh with the highest energy density for automotive grade batteries.
They've addressed the whole chicken vs egg problem with respect to rapid charging. Instead of waiting for people to build level 3 chargers, they are building their own network and locating them based on need, not just at dealerships (i.e. Nissan). Their chargers are also capable of much higher output than most of the other chargers (120-135KW vs 62.5KW (ChaDeMo) or 90KW (SAE combo)). Tesla has already had several years of experience with their superchargers and already has a large network of them along popular routes. By the time the low cost model 3 comes out they will be just about everywhere, even for out of the way places. Right now there are very few SAE combo chargers and they're primarily located in cities and almost none of them are located along major routes, making it impossible to do road trips without long charge times (especially with only 3.3KW charging!). There are some SAE combo chargers in the Bay Area and Los Angeles, but virtually none in between. Meanwhile I have my choice of routes with Tesla's supercharger network where I can drive from San Diego all the way to Edmonton Canada or to the East Coast. ChaDeMo chargers are also usually located in cities and not between them. They also tend to max out between 40 and 62.5KW. Tesla owners with the ChaDeMo adapter are reporting that many of these ChaDeMo chargers overheat and even start smoking, even when it's 0F outside because they can't handle the load, which is quite a bit less than what the Tesla chargers put out. Thankfully it looks like ChaDeMo is dying out.
Their skateboard design also helps maximize interior and cargo space compared to big humps under the seats and down the center of the car. They redesigned the car from the ground up for their Model S rather than taking an existing gasoline design and converting it to electric. I've taken my Model S places that would be impossible for just about any other EV except maybe the Roadster, and the ease of road trips with it becomes easier all the time.
They also showed that it's possible to design an EV with a low coefficient of drag that isn't butt ugly or looks weird.
The problem with GM is their marketing is so conservative that they compromise everything all to hell which is why GM's cars are ugly, have limited charging and limited range. I have little doubt that there won't be much comparison between the Tesla Model 3 and the GM Bolt. I think Bolt is what the customers will do when they compare the two.
