Arson attacks are actually an extremely French phenomenon, over 1000 cars are often torched a night on New Years EveAs far as I can tell it happened twice, 19 years ago and 4 years ago. I wouldn't call it a "common" occurrence.
Now, 1000 cars or 700 cars doesn't mean much, one would have to compare it to the amount of cars in France. For example, more than 150 000 cars burn each year in the US (probably not just arson, but it's not my point) which is 500 per day on average. But there are more cars in the US than in France.
