Also, it would seem that Toyota has sat back and done little to advance the Prius in the last 17 years (yes, they launched the Prius in Japan in 1997) in the eyes of the consumer or technically. I'm not a huge car guy, but I don't know of a significant change off the top of my head that has improved the Prius to inspire an owner of an older one to upgrade to a newer one. In comparison, it seems that Tesla is really trying their hardest to make constant advancement and take risk.
