The offerings from the other car companies do not currently surpass Tesla in any meaningful way I can see, and the assumption that the other car companie can "will into being" a technical marvel better than Tesla, seems to continue to be only an assumption.
I do not like Tesla or Musk very much, and would love for my next pickup to me an electrified F150, but none of the current electric offerings seem all that appealing if you aren't looking for a Tesla or can't reasonably commute in a Leaf. I am still skeptical I will be able to buy an F150 electric within the next 2 or 3 years, and would not be surprised to have to wait 3-5 years as they work out the kinks. I am not looking to plunk down 100k+ on GM's Hummer, either.
Dislike for Musk aside, I have to acknowledge Tesla is delivering a reasonable vehicle (discounting the stupid auto -pilot that isn't auto-pilot), whereas most other companies are still delivering small numbers of electric vehicles, but large marketing campaigns, which seem aimed at getting people to continue to wait on buying an electric car, because the next best version is always just around the corner.
