They pull out in front to escort you thru the dangerous areas. Think of them as your "presidential motorcade".
They will clear the road of hazards ahead of you.

Red lights are advisory in nature. If you decide to stop when you see them, it's your decision and you bear the delay consequences. :-). Look at the bright side. You have red, green, and amber. 2 of 3 let you go straight thru. So you only have a 33% chance of having to stop. On the other hand, if those intersections had stop signs, you'd have to stop 100% of the time, increasing trip delays by potentially up to 200% over only having to stop 33% of the time for a redlight.

Last option: Always drive VERY SLOW. The cars that pull out will be further in front of you, and the red lights have more time to turn green. This alos allows more time to take pictures of the idiots with your smart phone, and to call you insurance company and drop your deductible to zero before the collision.
