>Which state are you in? There are a lot of US states (like, more than 10) where cyclists specifically are permitted to go through red lights in some circumstances.

IIUC, cars are pretty much universally permitted to go through red lights at least 1/3 of the time -- right on red is legal (AFAIK) in all 50 states. In many states, left on red from a one-way street to another one-way street is also legal.

That's true, but there are additional special rules that apply to cyclists, and sometimes motorcyclists, allowing them to go straight at a red light under specific circumstances.

Depends on the state. Some are specifically "if there's a vehicle detection sensor and it doesn't detect your bike after 90 seconds", others are just "cyclists may treat a stop sign as a yield sign and a red light as a stop sign".
