Well I've found the first deficiency in our new 2010 Prius. The cup holder doesn't support the universal Starbucks standard cup. The stock Prius cup holder is waaaay too large, diameter-wise, and my cup tipeth over. Is there a decent adapter that can be plugged into the cup holder to reduce the diameter?
I find the cupholder to be exactly the wrong size for just about anything...wish it had those cool springloaded cupholders the Civic has. I always worry about my coffee tipping over, or if I'm using the front one, knocking it over when shifting, adjusting A/C, etc. Another part of the flawed interior, imo.
