Let me see: at 25 secs or thereabouts, he slows down a little and you start to get closer, you ride over 2 road markings saying SLOW **, he slows down some more because, presumably, of the traffic in front of him and you are still getting closer and apparently not slowing down until the last second.
As for the stop lights, I can't tell whether or not they're working, given the flare at the top of the picture. Me, I don't rely on brake lights but the size of the vehicle in front. I find that, if it's getting bigger, it's slowing down. Simples.
Your fault, Magnatom, for not observing and thinking ahead.
** I wonder if the road marking indicate that traffic can pile up at this point?
What I find baffling, Magnatom, is that you seem to have more incidents on your camera in a month than I had in the last 10 years of commuting into Bradford/Leeds/Halifax in the rush hour before I retired. I find it difficult to believe that even Glaswegian drivers are that much worse.
