Interesting thing about the problem with voice-recognition systems. I read elsewhere about how available voice-recognition systems are not very reliable, but there are improvements being made. Also, the part about luxury lines using brand name and price to distinguish themselves since the quality of non-luxury lines is improving so rapidly. This trend is not surprising, since a lot of these luxury cars are built by the same companies as the regular cars, and are usually upgraded versions of the regular cars. Ford-Lincoln, Nissan-Infiniti, Honda-Accura, Toyota-Lexus, GM/Chevy-Cadillac, and Mercedes-Maybach are some examples; although in the last example, both brands are luxury names. Maybe we could classify them as luxury and super-luxury.
