Even more devices to improve traffic flow needed

It is so nice to use the new flashing yellow left-hand turn signal in Kahului (The Maui News, July 1) and the roundabout in Kihei.

It makes the traffic flow so much more nicely and therefore saves energy and cuts down on carbon dioxide and its global warming effect.

Now if we could just get at least 100 more of these life would be even better.
