If you turn your turn signal on while there’s a car in your blindspot that’s just bad driving. The other driver has no way of knowing if you’ve seen them or you’re about to swing out on them.

Disagree. The purpose of the indicator is to signal your intention to others. Indicate first, then shoulder check. If you then discover a car in your blind spot, abort the manoeuvre if necessary or slow down to let them pass you first.

I do agree it's bad form to indicate when you know there is a car in your blind spot already.

Discovering a car in your blind spot should be a relatively rare occurrence if you are driving attentively.
