Would like to see GPSr take advantage of carpool lanes

I recently drove with my wife during rush hour in the Los Angeles area, where many freeways have car pool lanes. The GTM 20 did an excellent job of directing us off the freeway as it was backed up. But, this segment of I405 had a car pool lane and I thought I'd try it. Worked out great, most cars averaged about 10 MPH, we did 50's & 60's. The traffic service kept telling us to get off the freeway & travel surface streets (that were also very slow, with no car pool advantage, looser for us).
Hopefully a newer version of the firmware could use the fact that we were traveling at a decent speed, even though there was suppose to be heavy traffic (and there was for the non-car pool lanes). If using current speed is difficult to work in the algorithm, one other way to implement this would be to double-click the power switch, or a soft key could be defined and a new dialog box could come up, asking if you qualify to drive in a car pool lane. Here, many hybrids can drive in the car pool lane, even if there is only 1 occupant in the car
I know, car pool lanes come & go, but this particular one has been around for several years.

Hmmm... I've never used a carpool lane with my 660, but I see there's an avoidance for carpool lanes. Seems like if it's not checked, then it should use them, if available, like all the other avoidance options.

Carpool lanes
Good point, I never thought to dig into the settings. The 660 was unchecked in avoidances for carpool lanes, which means Garmin does something with them. I interpret that to mean don't avoid carpool lanes, use them if available. Traffic was checked. I should have unchecked it Traffic so it would have stopped telling me to get off the freeway.
I still feel Garmin could improve on handling carpool lanes & use them if the box is unchecked.

I think the problem there is that either the traffic feed would have to distinguish average speeds in carpool vs. non-carpool lanes for the same stretch of road, or the GPSr would have to assume that carpool lanes aren't affected by traffic. That assumption could be wrong, and I'm pretty sure the traffic feed granularity is per roadway & direction, not per lane or lane type.
The avoidance setting is simply a way of saying "I'm not eligible to use a carpool lane; don't specifically route me through one," but is still subject to an assumption about whether a carpool lane is necessarily a better route in itself.
Carpool lanes
I looked on my c340 and it had the check mark in carpool lanes.I removed the check mark and now will see what if any advantages will be gained.

My understanding (could be
My understanding (could be wrong) is that with traffic unchecked, you still get the warnings/notices but you will not be re-routed around it. You'd have the option at that point and perhaps the GPS would choose the carpool lanes if it was the best route.

CARPOOL
Have any one used the avoidance of car pool lane or HOV option in avoidance screens and successfully was detoured based on the hours of operation and regulation specifically in busy areas like DC..? Please share your experience, I am also interested to know if there was a way to modify the avoidance regulation table.
