They do have a range problem, but not in the way that you probably think.
If you take a look at the affordable EV segment, in the 2011 to 2016 era, it has been represented only by Nissan Leaf.
People are reporting anywhere between 15-30% of capacity loss within the first 45,000 miles.
The problem with battery powered vehicles is that there's a guaranteed loss of capacity after N charge cycles, which currently seems to be ~600-800 charges (77 miles of range x 600 charges = 46,200 miles)
Teslas have obviously not run into this problem yet, because their range is 200+, so you'd only start seeing significant capacity losses at 120,000 miles driven, which I'm guessing not many people have done since 2012.
But for smaller range vehicles this presents a significant problem: the commute you are able to make in the beginning of ownership may suddenly become impossible in just 3-4 years of driving.
And how do you get more range? You need more batteries.
In fact the first vehicle to solve this and have a decent enough capacity buffer at an affordable price will be Tesla 3.
On the other hand, this will put the nail in the coffin of the "not being able to scale" argument. In fact, Tesla 3 will be successful ONLY if they're able to scale.
