I still think that Lexus should design a high-tech coffee-cup adapter. It could be mounted on a gyroscopic device that will keep the cup straight up regardless of the incline of the car, you know, like the automatic headlight leveling system in my ES 300 (except that the coffee-cup adapter works in the vertical plane).
And the proposed Lexus coffee-cup adapter could have a little cable that hooks into the Lexus automobile main computer (next to the transmission lever?), and can be programmed to keep beverages either hot or cold, with a programmable temperature setting. Maybe even a liquid sensor to determine what the beverage is, and automatically determine if the beverage should be heated up or cooled down per the driver's previous decisions.
And if the software ever needs to be changed, you know, like that transmission software in the 2002 and 2003 Lexus vehicles, the Canadian Lexus owners can get the $1600 chip for free to fix the problem faster than U.S. Lexus owners can :)
