I was reading this WaPo Roads and Rails Q&A session and I noticed a disturbingly high number of people commenting that HOV lanes and congestion pricing was unconstitutional because they discriminate against people who can't find another person to ride with them, and it is unconstitutional to discriminate on public infrastructure.
I can't take my bike on the Shirley Highway. Are they discriminating against me? I can't even take a mo-ped out there. I sure as hell can't walk along the shoulder. You can't take your car on the Metro. Is that discrimination? Is it discriminatory for trail users to yeild to cars when they cross roads? I'd like them to tell me where controlled usage becomes discrimination, and why.
Now, I'm not endorsing HOV and HOT lanes (and certainly not any new construction of such roads) as any sort of a cure for our traffic problems here in Washington. But this is a very poignant reminder of how entitled we believe are cars should be.
