Does the lane function react to your indicators? I think someone here just mentioned that theirs did not. Also, I advise indicating well before you start the manoeuvre. This should show other drivers that you are not making a straightforward lane change since, indeed, you are not doing it yet.
A self driving car ought to be made able to recognise a cyclist with a jacket bearing a large camera logo, as it is on road signs, because cyclists report that this improves the behaviour of human drivers considerably.
