Speaking of the "silent" electric cars, my wife's aunt was tending to her small vegetable garden back in the early part of spring. She was working away when she heard a car door close, she turned around & the was a man standing beside what we later found out was a Tesla. The incident scared her because she didn't hear the car because it was silent. There days, she doesn't tend her garden unless her husband is sitting outside to watch for what she called "a ghost car". Luckily the man who was in the car had no ill intent, but you never know.
