I wanted to love this post 2x.
Don't want to speak for everyone, since I know local driving behaviors are different, but here, driving the speed limit on local roads is SOOOOO slow. People tailgate and honk at people going +5 the speed limit. So when I've wanted to test this feature, I've been riding the accelerator pedal the whole time I'm driving, which means by the time I reach a light, my foot automatically overrides the traffic light warning. It's been so useless.
This culture has to change as we move into autonomous driving. There is no way that any truly Autonomous car will be programmed to routinely break any traffic law, including the speed limit.
It’s possible that some limits are lower than they need to be and can be raised, but the cars will be obeying the law.
Given the needed culture change, I’ll be surprised if Tesla reduces the speed limitations going forward for new features, but that’s not as certain for driving aids.
