Waiting is the right thing to do.

Best advice I ever had, was to always use direction signals, but never trust anyone else's.

Thanks for getting me thinking about this. I've seen too many golf cart drivers do strange things lately. Will add this to my checklist of cautions along with using my turn signal in roundabouts so that the unaware/uninformed won't hit me.

Agree. The problem ....
 

Agree, but the trouble is that many, if not most, don't. Solution is "don't trust the turn signal indicators". Wait!

I don't have self cancel signals so I keep my hand on the indicator until I complete the turn so I don't forget.

Looking into getting a buzzer.
