On regulation, I believe regulators are prone to bending to the will of local constituents. Uber was very effective at galvanizing voters when local markets were threatening legislation via the app. I imagine the many millions of people that will own a Tesla in 2 years will have no problem clicking a “message your local congressman” button on the screen to get this approved in most markets. It won’t matter if NYC, Portland, San Fran and LA ban it.
Of course, the data will have to fully support the safety of Tesla FSD. I’m curious to watch it play out.
