The other day I saw a car parked in Boston with one of these:
And that got me thinking, I hadn't seen one of those things in a long time. They're pretty much gone nowadays. I used to have one in my 1988 Toyota Camry, but when I bought a new car in 2000 it never made the transition, and I'd long since forgotten about it. So my question is, what happened? Were they not really functional, did they just not work? Have they lost out to more advanced tinted window technology? Were they just a fad? If you have answers to any of these questions please let me know.
