In my area I find that the cross-traffic ones are poorly implemented. I'll drive up, come to a complete stop, the light will change for me and will already be back to yellow before I clear the intersection. This forces me to always stop when there was no traffic on the preferred route. It also means that if there is a car more than a few car lengths ahead of me it will change for them and force me to wait a full cycle even when there isn't traffic on the preferred route.

This shouldn't be a hard problem to fix. Sensors just need to be installed farther from the light to detect approaching vehicles earlier.
