HOV lanes are another example of a Democrat idea that fails. Originally implemented during the gas crisis, it does nothing to save fuel. Where I live, it is mostly unused during rush hour, while the other lanes are backed up. And then like magic, when the lane opens up to other traffic, within five minutes traffic starts flowing again.
A little over a year ago all the HOV lanes on US75 in Dallas were blocked off. Totally unused. Never did find out why. They just closed them leaving two to three lanes unused.
