What he authors of this article fail to consider is that most who ride public transportation do not own cars and in 2040 most of them would continue to take the train.

Hawaii or Oahu did not step into the 21st century traffic flow improvment on Fort Weaver Road to Eva Beach. 
After road widening, traffic signal lights were synchronized. 
Synchronization of signal lights is hi-tech except by 21st century standard it is not      .
Except vehicles in Hawaii, Oahu and Fort Weaver Road, all have to stop to allow vehicles to make a left turn.  
Thus, vehicles in Oahu, Fort Weaver Road can not and can never ever go thru 4-5 intersections without stopping for vehicles to make a left turn.
In Utah and other states, vehicles breeze thru intersections without stopping to let vehicles make left turns. 
Drivers in this island may never experience going thru an intersection without stopping for left turning vehicles. Nor green light most of the way!!!
