Totally agree - this story is only really interesting because it is Tesla, and it seems like they could have worked out that they wouldn't be suitable ahead of time. But equally this looks like a trial and maybe they just had to do the trial to dismiss it as a silly option.
It would be the same if some police force decided to purchase BMW Mini's, spent $100k retrofitting each for police work, and then complained that they were too small after the fact.
Total own goal!
