If the junction had visibility, it would be boring

Here's another example of how Bristol is leading the way in community-initiated traffic calming.

By parking across the junction,approaching vehicles cannot see ahead, and are forced to slow down and proceed with caution.
It also forces cyclists to merge with the car traffic, so eliminating the dreaded "car turns left over bike" collision, which is such a recurrent problem with bike lanes and other car/bike segregation experiments.

Many thanks to blue van WR56FME, sponsored by TGI, for this piece of much needed traffic calming.
