Dropping a trailer vs waiting for it to be unloaded? I dunno. I agree with what your saying. Just moving stuff is obviously faster than waiting around for loading and unloading. At what point does the idle electric truck start to cost less than a simple trailer.
There's an "easy" solution to that too, you make it a flat bed electric self-driving trailer which takes a container similar to sea shipping containers on top.
Then you don't:
- have the unnecessary truck cab in front
- cost of the trailer being unused while loading / unloading
- potentially drastically change shipping containers received from over seas.
