Yes, this was quite a common occurrence about 6 years ago, but since then seems to have fallen into disuse. I hope it isn't starting up again. It's complete nonsense, and you mustn't let it scare you. It was not connected particularly to driving, it was supposed to be placing a sense of evil in particular places. The thing is if you let it frighten you, you will be conscious of this when driving, and will be more likely to have an accident. I suggest you disregard any further nonsense, and suggest that you find more stable friends. Take care.
