It's definitely not just outsiders as you (and I) can attest; I went with that line of argument to try and convey some sense of urgency about the problem. It's easy to dismiss internal dissent about SV libertarian groupthink as not important, but "outsiders" have the potential to bring the party to an end if they collectively get really grumpy about what we're doing. I thought that might be more motivation.
- thinks it's OK for neighbors and local government to have a say in whether people run a hotel next door, possibly sharing a roof or even a wall
- thinks it's OK to require pretty reasonable background checks ala Austin for taxi drivers
- thinks it's OK to have some safety regulations around self driving cars sharing our roads beyond hey, it worked in my car on this specific stretch of road so, you know, yolo
What about those people? The people who WILL die in car accidents next year unless we do something about it. Screw them, right?
The question at hand is: Does this specific piece of equipment actually work as described, and move us towards that goal, or is it a piece of cobbled together junk that will cause more accidents? If you want to sell this specific piece of equipment on the consumer market, you'd better have a good answer to that question, and be able to back it up with more than "hey, it worked for me this morning!"
