First, let me say thank you on the Build Back Better.... I know you burned up the lines between Ottawa and Washington, D.C. The industry thanks you for your effort there as well.
Yes, that technology does exist, and it is installed in most, if not all, of the new vehicles. I'll just use the anecdote of the current vehicle that I'm trying to get tracked through law enforcement. Usually when you deal with the company that's tracking the vehicle, it's either the automaker or the automaker's third party partner. They are getting a sight-unseen call or communication from the owner. You do some verification, yes, but you have no way of knowing whether that person's intentions are as noble as they say: “By the way, I'm reporting my stolen car. Please go track it down.”
There's always a link between that company and law enforcement. They don't communicate back to the owner.
