OK,
your biking to work say and flying through the traffic when some "person" sees that you are and decides to pull the car right over to the curb!
the mentality of some people....
I know this does happen, although its really rare for me to see it. On the occasions that I have experienced it it is fair to say that a motorcycle was in the offside and the car moved over to "help" the motorcycle without checking the inside line.
Filtering to the offside does remove this risk but I appreciate its not always possible, as the cycle path is on the nearside.
I actually find this more prevalent when on the motorbike especially at traffic islands where some drivers will stubbornly sit close to the island to stop motorbikes getting through on the offside and then glare at you when they finally crawl forward past the island and provide (begrudgingly) enough space to pass. The temptation to drop to the right of the island is very strong in those situations and I often feel that these drivers are trying to tempt you to break the law just to reinforce their opinion that all motorcyclist need their wings clipping.
These are the type of people who worry me., they go through life with poorly formed, bigoted opinions and cling to every opportunity to try and make their view of reality true. I work with a guy just like this, he makes unbelievable statements sometimes and expects everyone to agree but instead is met with blank stares and exasperation. He then stomps off grumbling that the world is going to hell in a handcart!
Its always someone else's fault. It cant be them that's wrong.
