It seems Honda selected California as the mecca for Clarity PHEVs. This article advises that Honda will only have on-hand Clarity inventory at California dealers, and people in other states will need to place special order (at higher price): https://www.carsdirect.com/automotive-news/honda-shifts-focus-for-clarity-plug-in-hybrid-squarely-on-californiaI'm stunned that Insight is 41% of Honda's electricfied sales. Here in SoCal see tons of Clarity Plugin and Clarity EV every single day especially in the Carpool lane. The last Insight I saw was a week ago, a courtesy Vehicle from a dealer. I rarely see them.
Perhaps this is California and Clarity is favored because of carpool lane access. I can tell you all the Clarity owners at my work bought / leased them for carpool lane access and only drive them to commute and don't drive them on weekends.
At my work, we have 3 Clarity's, eGolf, i3, Bolt, Model 3, 2 Prius primes... 0 insights, 2 ioniqs hybrids. Again showing the dominant Clarity over the Insight. There are also some CT200h and Gen 2 Priuses... But thats all old stuff.
Clarity's are common on the freeway on weekdays, but a rarity to be seen on weekends, relegating them to commuter vehicles. The Insight is a daily driver, so I would expect to see more of them, but sadly there are not.
