It’s not a matter of whether your taxes paid for it, it’s a way to try and relieve the congestion on the roads, and is also illegal to use unless you are a legitimate car pool. Did you think Hillary shouldn’t be prosecuted too? That was just as illegal. Maybe you think Bergdahl shouldn’t be prosecuted. Or any of the people who have killed over 600 in Chicago this year. Maybe we should just ignore every law in the country we don’t like. After all we paid taxes to keep the country running, why should we be bothered by its laws? I pay taxes every time I buy anything except food. (No food taxes in Texas) So just because I pay taxes I should ignore the laws? What other laws might you advocate ignoring? Murder? Theft? Armed Robbery? Rape?
Depends on the state. In Utah, driving through the Salt Lake metro, it only depends on occupants, or you can use it with a motorcycle. Still, it's BS. Same with public buildings designating parking for Smart/Electric cars only. It's a public highway, financed by excise taxes. Unless they give me a refund for what I'm not allowed to use, I should be allowed to use it. The traffic flow BS is just that, BS.
Your other examples are nonsensical.
