Its not quite the same because of the fact that, for us, the answer lies in the Charter of Rights and Freedoms. The fundamental difference in the call center concept is the fact that the recording is used to improve communication and customer relations. There is no fishing expedition where the result is solely being sought in order to determine if the person commited an illegal act by some means...and then after you invited them to park your car for you.
The hiccup hits the Charter long before we get into the covert, or even known recoding of a persons actions. You might also believe this might be similar to recording people on your property, but it isn't because when you provide your car to a valet, you have now expressed a specific invitation for them to be on your property. Even saying that, this would not facilitate such because your vehicle isnt deemed to be your property in the same sense.
My guess.... they shut down this option in Canadian cars, at least until they can sort all the legal implications out which will most certainly not be within this model year. The unfortunate part is the 'Stop Ship' because, this mat be tantamount to say... GM forgetting to put the seatbelt warning stickers we hate so much on the visor. I believe in such a case they WILL NOT release that car for sale until the issue has been rectified.
Just my opinion and as always... I hope to hell I am wrong! This is definitely enough for me to remove the PDR when and if i ever hit 2000.
