An oldie, but a good reminder of how long some of these development cycles take. Since GM (along with everyone else) is headed into EVs.... will that be the breakthrough market..... 30 years ago, they cited the same need that SPD addresses today.
To me, the killer apps are sunvisors, rear side windows and then dynamic glare control on infotainment screens. Sunroofs are just a gimmck AND windshields already use laminated glass. We're getting close, one more model with decent volume gets us to breakeven, but I doubt it's a sunroof that drives demand-- sun visors should do it.

Google does have a 2016 patent for a head-mountable VR device with adjustable transparency. The device could be controlled via cell phone.
The remote device may be any type of computing device or transmitter including a laptop computer, a mobile telephone, or tablet computing device, etc., that is configured to transmit data to the device. The remote device and the device may contain hardware to enable the communication link, such as processors, transmitters, receivers, antennas, etc.
The optical element could include at least one liquid crystal cell, an electrochromic cell, a suspended particle device, and/or a switchable mirror. The optical element could be operable to change the transmittance of the optical element and/or the optics.
