You don't seem to get the gist of my post.
The most important part of pushing the industry forward is batteries, the car is largely irrelevant as most of it has existed before. Tesla is an EV car maker (like just about every other car maker) , I am pretty sure they don't do much if anything to further the science of energy storage. Its mostly third parties.
As for the car above, I didn't say it was trying to compete with anything. I was merely pointing out that building an electric car is easy, that is, what Tesla Inc does is relatively speaking easy, from a science/ technology point of view. Just google "DIY electric car" and you will see plenty of examples.
It is theoretically possible that a person with the right patent could literally own the whole EV market if the battery they created was far lighter, far faster charging and far cheaper than anything on the market. Just like I think Dyson could have captured the whole vacuum cleaner market with its patents that it ultimately decided to license out (which is the logical thing to do)
Like I said before 1400 km is the farthest I have driven in a day, but obviously if you can do a quick recharge like filling a petrol tank, 500km would be just the same. This is really simple stuff, I don't understand why you need such detailed explanations, all of this should be obvious, but I guess I grossly overestimate the people around here all the time.
