Not sure if i've explained it well, but the H was a company logo, on the passenger side door (not the vehicle manufacturer logo). It's really hard to see in the vid, but i recall it at the time. I think i've seen the logo before, but no idea what company it is.
I want to send the company the link to my video and say "Look at this dangerous prick!". I just don't get how people think that running red lights and that kind of thing in a signwritten company vehicle is a good thing, especially with the prevalence of dashcams these days.
