I would never report anyone for anything like that, but that's just me. I've reported two things in my time, one a truly shocking courier van that zigzagged, lane hopped, close passed for a solid 2 mile stretch (lights kept me with him). The other was a taxi that tried to pinch me at some lights, as in he saw me, pulled across, I had nowhere to go but forward so I accelerated, he then accelerated as close as stupidly possible, tooted, shouted out of his window.
Both instances were genuine bad driving. Not mistakes, lapses in concentration, or errors of judgement.
EVERYONE makes mistakes. Peds step off kerbs, cyclists gamble on amber just as cars do, cars forget to look in their mirrors, cyclists forget to signal, the list goes on.
We cant expect infallibility from anyone.
I feel we should all keep a mental ladder of escalation. You cant bring out the big guns of reporting that for 'Dangerous Driving' otherwise the really dangerous stuff is lost as white noise. We'll all be accused of crying wolf before too long.
That said, I know that being on that road, having it thunder past me, knowing that I had stopped, it would have felt a bit 'more wrong'.
Aaaaanyways... 1hr 20 until hometime.
P to the S... I have never seen a 'bent on my commute (Lon-Sidcup/Hextable)
