Munro is a bit of an old dinosaur that isn’t on the same planet as Tesla. I listened to most of that 90 minute video where he was kibitzing with 4 other guys. I lost track of the number of times he said he just didn’t understand why Tesla did things a certain way, implying that if HE couldn’t understand it, it must have been for a dumb reason.
For example, he crapped all over Tesla’s back end panel or trunk design saying it had been made with 7 parts where it could have been made with one and weighed less. He was completely baffled why it was done this way. His problem is that he has no clue how Tesla really works.
Assuming that it was indeed a sub optimal design (big assumption), my guess is that they ran out of time to optimize that trunk assembly and they’ll get around to it in 6 months. Which is exactly what Tesla did with the Model S. The 2012 Model S and 2014 Model S cars, each ostensibly the same, have quite a lot different under the hood, so to speak. Tesla has been constantly under the gun to get new product lines out the door, but they make up for deficiencies by constantly improving their design and manufacturing processes.
Also, these dinosaurs go on about panel gaps. Yeah, there are some, small, minority of people who care more about panel gaps than the awesome way the car drives, so maybe a Model 3 isn’t for them. There are plenty of people who do want one, panel gaps and all.
Tesla makes it’s fair share of mistakes (as do the other car companies!), but it’s their speed of correction and speed of innovation that makes them stand apart.
