Maybe there are other 'if's to consider but these are the main ones I can think of.
All cyclists, in an ideal world, should know these rules off by heart and abide by them, but we all know there are some who don't. The question is, how to represent these rules in a succinct and unambiguous manner, in the form of a notice on the back of the vehicle? Attempts to fulfil this need, as we have seen from this thread, don't really get the right message across. Any ideas?
It's the vehicle's driver's job to check before turning left that no cyclist is on their inside, it's as simple as that.
Cycles are allowed to filter on the left, indeed, they have
to, to get to advance start boxes.
We have to watch out for bad drivers, granted, and sometimes anticipate bad driving, I certainly do, but the legal situation seems pretty clear to me. It's the driver's
job to check before moving left, just as it is their job to check before moving right.
