There's a lot of hate and anger here directed against the driver, who was of course himself full of hate and anger. He should rot in hell etc etc, it's all very American. None of that will solve anything. This is about systems. Paris is too dense for cars, let alone SUVs, but humans like their cars and will buy them and use them if we don't decide collectively to prevent it. The tragedy here was not that one entitled guy blew a gasket and did something he surely regretted instantly, it's that we all, together, allowed this situation to occur. A rush-hour boulevard crammed with too-big cars, in a city which is already as dense as a hothouse, in a country with increasingly angry and polarized politics. The problem is not individuals, it's systems.

I'm sorry if if this is too sophisticated an argument for this community, but I speak with direct experience of the subject at hand and I would like to see the problem actually solved. Anger directed at this individual miscreant is IMO an almost irrelevant distraction that will not solve anything.
