My car is always parked in the garage, but the false alarm happens
rarely.  Today the car was idle except that I opened the door twice to
insert and remove a USB drive to take my monthly log dump.  The false
alarm happened some time after the other activity was completed.

You requested: CAN bus dump (can1) ID #100, B1=0x83,0x84,0x85

Is this the command you intended: can log trace 1:100

Is there a way to filter on B1?

I see that the message rate is pretty high for watching messages flow
by on the screen, but the data rate was 1248 bytes/second.  Is that
too fast for writing to the SD?  That's 100MB per day, but with some
GB of free space on the SD that should be sufficient for the rolling
log.

Or is the rate much higher when the car is in operation?
