I wouldn't say they were day trading vehicles. Just look at the open interest and you can see that a lot of contracts are held overnight. Big moves like today are caused by longer term traders liquidating not by scalpers (who are active every day). Of the day traders I think a large proportion must be people who just make one or two trades per day.

I would agree though that if you actively day trade a single market you don't want to be running away from volatility. You need to learn how to trade it.
