I don't like systems that automatically switch the turn indicators off, traffic conditions are not always predictable, and there can be situations when you need to have indicators running a little longer. Motorbikers are always disadvantaged in visibility, they don't need additional difficulties...
IMHO, a simple acoustic indicator should be the best solution (not rocket science, I know), leaving to the driver the decision to switch the indicators off.
