So how does insideevs come to their estimate?
While we will never fully divulge the exact methods, we would love to provide some clarity to help everyone to better understand the situation. Tesla does not break down monthly sales figures by country. So, they do not release delivery data for the U.S. at all. Instead, Tesla offers a global look at the end of each quarter. For this reason, our monthly Tesla delivery data is estimated. It's impossible to be 100% accurate. One primary source of data is VIN numbers and additional delivery information reported by Tesla buyers around the web, social media, and to InsideEVs directly. t the end of each quarter, after Tesla releases final sales numbers and global data, we adjust our U.S. numbers as needed. We only make adjustments at the end of a quarter and after global registrations are in.
I would love the insideevs estimates to be true but I don't want to be caught in confirmation bias. I would love to see actual registration data similar to netherlands, norway and spain for US states.
