After finishing reading, Elon, by Ashlee Vance, I saw my first Tesla on the roads of Leadville, Colorado, the day of the 100 mile mountain bike race, during summer of 2015. Over the following year, I thought it interesting to start recording every Tesla I saw on the roads. I would use the information as a proxy for electric vehicles becoming mainstream. If there were Teslas, there would be others trying to get a slice of the pie too.

Data collection was simple for the first two years - then we went to Norway. After 77 sightings during our one day in Oslo, I knew the potential for transformation was huge.

Now, the Model 3 has launched and I've started to see them hit the Portland streets.
