Thanks for your perspective. There are lots of people who like to shoot down technologies simply because they're ignorant of all the scenarios that exist. They see only one possible use (e.g. long haul trucking), correctly identify that the technology won't work in that scenario, then proceed to dismiss it entirely because they're unaware of the myriad of other applications.

The problem with these people is that they will go to great lengths to explain to you why your technology won't work in their specific application and feel smug because they think they've cleverly identified a flaw that you didn't think of.
