Even if you have a pretty good feel for normal red light duration, it's not always possible to know how long is left on the cycle.

Do you start slowing early, in hopes that you'll still be rolling when it turns green? Or do you gamble that green will come sooner, and brake late?

It's quite the conundrum.
