Here's the scenario. Rear off-side indicator stops working so I check the bulb which turns out to be fine. I decide to take the car to a local garage for a diagnosis. The problem is that the(short) journey involves an unavoidable right turn.
Mindful of the non-function rear indicator I do what I believed to be a text book manoevre. I checked my mirrors and noted a vehicle about two lengths behind, slowed down and lowered my window. With a hand signal I indicated my intention to turn right and eased towards middle of the road. The said car behind me then passed on my near side with the driver winding his window down and gesticulating and mouthing off aggresively.
I believe that, under the circumstances I used my common sense and took the only course of action I reasonable could.
What would others have done?
When I was a kid my dad's car had semaphore signals that were always sticking but I learned to drive in a car with indicator lights. Nevertheless the driving test required me to demonstrate my use of hand signals at some point. I was complimented by my examiner on the flamboyance of my waving hand to indicate slowing down, but he still dumped me on failure to make adequate progress while negotiating a notoriously difficult junction at a very busy time!
Shame to state the agonisingly obvious but if the car basically wasn't road legal then it shouldn't have been out driving. In practical terms, personally I'd probably just have driven to the garage with a bit more due care and attention than normal but without any of that hand wavy stuff. In legal terms you'd probably need a towtruck.

Get with the beat. Your understanding of modern indicator technology is lacking.
Clearly you should have opened the window and repeatedly thrown your arm out sideways and pulled it back in again until the turn was complete.
