The research indicates the 'best' system is 'speed control alone' - perhaps not surprisingly (see the report for definitions of the systems).
'Speed control' would be worrying because it would give you a dead throttle, which means losing the option to accelerate out of trouble. There are rare-but-critical circumstances in which the safest course of action is to accelerate out of trouble. And I'd rather break the speed limit (briefly) than have an accident. Car drivers mightn't realise how vital this option can be on a bike.
Usually, riding systematically should avoid trouble through observation, anticipation and planning. But there are circumstances in which the safest action is to accelerate out of trouble.
