Well there are people who have something to talk against. Like there was a petition with 35K people to white house to attack Mars. 
Every system have some drawbacks.
HOV lanes here in NYC, NJ, PA are blessings. HOT lanes.. If one don't want to pay don't get inside.. Its one own decision. But if you pay you move fast as there are limited cars there.
All those who say these are lexus lanes then will also say why Buggati is making veryon s or Lamborghini making aventador if there are only limited people buying it.. If one goes in business class its the reason he can afford.. 
As far as the HOV or HOT are concerned these are very beneficial to people and they pay to reach fast.
The article I sent was just an idea for you to understand what is HOT.. There are numerous studies which have shown benefits of both systems..
As far as stuck in traffic.. The answer is use car pool.. Or public transportation. I have been car pooling 4 people for 3 years near my old office. We saved on gas, tolls and used HOV.. Its really helpful..
