Just to show that there are lots of sensible responsible drivers around who condemn idiots who endanger cyclists here's a thread on another of the car forums I'm a member of.
What's amazing about that is if I was that cyclist I'd have shrugged that off as a non-event! I've had them alongside and starting to pull in! So it's quite impressive that a car driver actually thinks anything is happening there.
(This morning I had a guy pull out of a road to my right turning right and slam on as he saw me, before waving me past, overtaking and turning right again just 50m further up - you'd have thought he'd have hung back out of embarrassment! However if I ever need any plastering doing PT Plastering of Warrington won't be getting my business.)
