It really annoys me, when people drive around without tax on their vehicles when they know about it. Recently I spotted a van that had come into my work to collect building materials, this van and its driver have been in a fair few times before and he is doing building work for the old branch manager who moved up to a better job.
When the driver was questioned as to why he had no tax on his van ( Ford Transit) he responded with "I just don't have time" I mean come on, what kind of excuse is that to not pay vehicle tax. I know its a blatant rip off, but we all gotta pay it.
However I'm torn on what to do. Knowingly let him get away with it or tell the police, let them deal with him and potentially a kicking or what ever from the driver since he might know it was me who said something ( or one of my colleagues)
