I completely agree that bikes take up just as much road space as a car (at least when other cars aren't riding in our space) so I understand the 2 up rule for HOV lanes. I feel no entitlement to use them.
The only arguments that come to mind in our favour are...
1. Motorcyclists are in the vast minority so getting them out of regular traffic is a plus provided that the HOV lanes have capacity for them (as mentioned the HOV can get congested due to slow drivers and single occupant vehicles).
2. Motorcycles MAY fall under "green" vehicles. There's been a lot to debunk this but generally speaking bikes tend to have better fuel economy that the average car. This means fewer fillups and less exhaust fumes venting into the atmosphere. Unfortunately, a lot of bikes also release more pollutants per volume of exhaust gas.
