Morning,
You might want to consider what you are doing, especially what you are posting, as outsiders including the police won't necessarily see things the same way that you do.
You have said that you are intentionally recording him to catch him being offensive to you, this starts to become problematic especially as you now have two videos of him not doing much.
Imagine going to the police station and reporting this,
The officer says can I see the videos, you produce three that show issues.
The officer then asks why you have three.
You say that you have been recording this driver every day.
The officer then asks so it doesn't happen everyday and you say no.
The officer then asks if have you spoken to the driver and you repeat what you have said above. So you have had contact with the driver who appeared from your account to act quite reasonably. If this exchange is recorded then it tends to suggest that you are at least part of the problem, if this exchange is not recorded then the question of why not would likely be asked.
You've get the reg number, you have spoken to the driver, so maybe it is time to either let it go or report it.
To me it is starting to look like an argument could be made that you are harassing him. :-)
