With a bit of care one could probably arrange a bout of "fatal embrace' with two cars sitting growling at each other alternately, with perhaps the odd bout of 5 minutes of siren sounding every now and then. Met a man tonight whose newish car had stalled with a deadish battery and wouldn't restart. It sat partially blocking a main road at night with its alarm sounding in slowly descending tones as it drained the last of the battery's life blood - no doubt to remind him how annoying modern technology can be on occasion.
