### Comment:
Although these have been seen all around the country, although there are videos of them thousands of miles away, there's something that will prevent the technology from being scaled up from every other electric motor and batteries. Can you explain what that might be?

### REPLY:
There's absolutely no technological reason why you couldn't make an electric semi. My doubts have to do with Musk's ability to execute and Tesla's ability to spin up another production line (especially that quickly), not with the technological feasibility of the product.

### END.
