The Tesla cut into the lane with 3 car-lengths or less behind it and rapidly decelerated. The two cars behind are going to collide because the first one, who was safely positioned before the Tesla changed lanes, didn't have time to react and the second car was probably not able to either, because the brake lights in front didn't come on until too late. Then, there was a couple cars that were probably tailgating, and finally the whole thing is a snafu.
I can't tell if the people making these comments about the drivers behind the Tesla being responsible are such defensive drivers that they never leave less than 6 seconds in front of them, or they're tailgaters themselves, or just being mendacious.
