No GPS/maps system seems to offer the option for FasTrak or carpool lane.
No GPS/maps system offers a way to tell a driver in a carpool lane if they have to change several lanes to the right to merge onto another freeway, or if there is a new carpool lane opening up to your left that takes you directly onto the next freeway you way to get on.
This is what happens when you have an oligopoly (Garmin, Google/Waze, Apple) and everyone's product, design and sales people are in the Valley or Tel Aviv and not more driver-centric cities with much more traffic and orders of magnitude more route options like Los Angeles.
