Self cancelling indicators that work on time are not to difficult to retrofit, I made some back in the ‘70s, but self-cancelling that takes in distance and/or speed is a much more daunting task.
However it is quite simple to fit an optical or audible indicator that remains off as long as the brake is held on. Normally when stopped at a junction you will be holding one or other of the brakes on. When you move off, you release the brake and the warning comes on to remind you to cancel. Simple.

Subject: Re: [DucatiST] Re: ST3s Signal minder
Nick's idea is easy to carry out, simple and cheap. However, If it's
bright enough to be obvious during the day, it will need to be dimmed
at night. I think that the only useful 'signal minder' is the algorithm
that BMW uses. I can't remember the exact figures, but it has two modes:
If your speed is over 50 km/h, then it cancels after 15 seconds. If your
speed is under 50 km/h then it cancels after you've travelled 300 metres.
On the very rare occasion when this wasn't enough, I've always found it
easy to notice and restart the indicator. I presume that other manufacturers
don't want to pay a royalty fee to BMW. I wish they would. (There's no need
to go the whole hog and have the separate left and right indicator buttons:)
