Longer Yellow Lights
Increases the length of time that a yellow light lasts at a traffic signal from 2 seconds to 4 and a half seconds.
To me, 2 seconds just felt like it went by too quickly, if you're dragging a particularly heavy load it can be difficult to stop in time for the yellow lights, and easy to receive a fine.
In real life, yellow lights can range from 3 seconds to 6 seconds, so 4.5 seems like a good middle ground.
Tested on 1.0.0s but it should work on future versions too.
