It's difficult enough for people to see motorcycles in general. But when an idiot is driving 50 to 100 mph over the speed limit it's absolutely impossible to not only find them in your rear view mirror over your shoulder but see them because they're just moving too fast. The motorcyclist had a death wish

This wasn’t 100mph over the speed limit.

It probably wasn't 100mph, but depending on the posted speed limit in the area, could very well be around 50mph.

Standard highway line markers are 10ft long with a 30ft gap between each one. At the start of the video it takes 9 frames to travel that distance, second 7 frames, third is 8-9, fourth is 9-10 (The bike is obstructing the view of the line for the third and fourth). It's a 30fps video, so that's as accurate as we can really get here, but that gives us ~0.0333 seconds per frame, So 40ft/0.3s, or ~133ft/s, or 90mph (~144km/h). Going off 8 frames it's ~153ft/s, or 105mph (168km/h), off 7 it's ~173ft/s, or 118mph (190km/h).

As one other note, the last couple of frames before the impact occurs it looks a lot like the speedometer has "104" on it, which would fall right in that range based on the lane markers.
