Did I inadvertently unlock someone else's car doors?

I went out to get Bunny and myself some lunch, and as I was leaving, I used my fob to pop open the trunk to store the food for the trip home and I noticed that a car near my own honked briefly and flash its headlights. Odd, I thought. I then used my fob to unlock the car, and again, the nearby car honked briefly and flashed its headlights. I then used my fob to lock my car, but this time, the nearby car sat silent. I unlocked my car again, and again, the nearby car honked and flashed its lights.

I know that fobs have a decent range on them but I always thought the data sent was unique per fob. Maybe not? And then there's the fact that fobs can help criminals steal cars! That's more surprising.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site: https://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

https://boston.conman.org/2000/08/01

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
