IDK if the accidents are being caused by people wanting to take pictures, I remember driving through Oklahoma on i-35 northbound during a storm. It was difficult to drive for several reasons, the highway had flooded, there was sideways rain, vehicle shaking because of strong winds, and traffic caused by storm. There were cars trying to stop on the side of the road, the problem was there were too many vehicles and just plain confusion, some vehicles on the shoulder lane were stopped completely and others that had stopped were trying to move away this with poor visibility and freaking stopped big rigs on the main highway blocking some vehicles that wanted to get away, all this while a tornado was on the side of the field.
