I think it was a mix, some bad and some good. HOWEVER, Tesla is so far behind the rest of the automotive industry in the number of commands. Even in my old FORD do dial the phone all I had to do was say the name followed by which line such as "Call John Smith - HOME or "Call John Smith - Mobile" and it would dial. I did not have to take my eyes off the road and select which number.
Now the ford on navigation and related commands was terrible. Tesla is much better than the Ford was on it's best day.
