Actually, I am not generalizing all the KARWA drivers nor give you the impression that they are all bad. My point here is that, this guy is risking one's life as if someone is hiring him to do such thing. Don't get me wrong, this is not some sort of paranoia. If you are a very cautious person, you can easily differentiate if somebody is just behind you and driving normally from the one who's driving and there is an intention to harm you.

Anyway, I hope that these occurrences will not happen again. Just be cautious and attentive evrytime. :)
