Who would knowingly steel a Volt, or a Prius for that matter????
It was a 2005 Prius, and as far as I know, the thieves were not apprehended, so it's not clear to me what the motives were, or who they were, but my for-the-heck-of-it kind-of-far-out-there theory is that some kids saw the extensive signage on the car and might have thought it looked like it was modded for high performance and speed rather than for ultra-high-efficiency.
On the Volt question, given how wired and dialed-in and traceable the car seems to be, I have to agree the car is not a great candidate for getting stolen. (Note, however, that there are special cases. In my case I am close enough to the border that it slightly raises the level of concern of mischief coming to the car, although I should quickly add that I have no specific reason for being concerned about matters - I don't remember friends or neighbors indicating such things. I haven't yet checked the local paper to get a sense of this.)
I spoke yesterday with OnStar and it sounded like if I want the deal where they will track down the car if it is stolen, I will have to get the $25/month subscription (never mind all of the complications and temporary deals). They do apparently offer "add-ons", and I would have been ok to get the no-fee OnStar and then pay $5 or $10 per month for that feature separately, but they don't seem to offer that. So, I sent an email to my insurance agent (Farmers) to find out how much of a discount they will offer for me to keep the track-down feature activated, and if it is not much, then I will consider getting rid of the feature. (I do want it, but I am a bit tired of getting nickel and dimed).
