Well, that is the law, at least in Oregon.
In Rhode Island, West Virginia, Louisiana, and Tennessee; drivers cannot be in the intersection when the red light appears. In 37 states, if a driver enters the intersection on a yellow light, they have the legal right to continue through the intersection after the red light appears.
In Oregon, Nebraska, Iowa, Wisconsin, Michigan, Mississippi, Virginia, New Jersey, and Connecticut; the law is nuanced. In these states, drivers should stop when the yellow light appears, unless it is not safe to stop. Much judgment by you and the observing officer or camera.
The states of Arizona, Nevada, Nebraska, Oklahoma, Michigan, Tennessee, Virginia, Kentucky, and New Hampshire state in their driver training manuals that drivers are prohibited from accelerating to enter the intersection while the light is yellow.
I find it amazing that the simple rules that I learned all those years ago is not in force everywhere.
1. If the light is green, you may enter the intersection.
2. If the light is yellow, you may enter the intersection, but a red light is coming.
3. If the light is red, you may not enter the intersection.
4. A car in the intersection has right of way.
Until FSD V12, that's the way it worked. It matched the way people drive. It's ironic that V12 now doesn't drive the way people drive. This is the sort of thing that encourages me to not use the system. It's dangerous to brake like that.
