It's all down to your eyes "shutter speed" and relative movement of the object.

yep, its "after image" which creates the "trail". Some might remember as youngens, writing their name in the air with sparklers? its the same thing.
Grab a screenshot of the sim tracers and you'll get bright little dots, not streaks
What people need to get away from though (and I'm not having a go at you or anyone else... its just, this is where it came up). the eyes do not have shutters or a shutter speed... it is a constantly streaming input.
