While on the subject of highway driving, I *desperately* need the entire driving public to understand the difference between these two signs please and thank you.

@TechConnectify can’t wait for a Conextras on zipper merges

@sass Hot take - the only way we're gonna make zipper merges work is if the stop telling people which lane ends.

If a sign just said "Caution: Lane Reduction in Three Miles" we could force people to take turns.

But saying "Left lane ends" means planners will plan, they get over, then they're annoyed at the people who didn't plan, they don't let them in, yadda yadda.

@TechConnectify @sass @TransitBiker Or do like they do in NY and put up signs that say “alternate merge.”

@AlliFlowers @sass @TransitBiker Sure, but still - you can't let people in on which lane is ending. Otherwise people will understandably think "why didn't these people get in line back when they had the chance" and not let the latecomers in.

It needs to be a surprise to get people to actually cooperate.

@TechConnectify @AlliFlowers @sass ooo, I know! “Lanes merge” and instead of the “ending lane” pointing into the “continuing lane”, make it more of a converging fork? The merged single lane then is a bit wider for a stretch to allow people to figure out spacing. This could also allow vehicles like semi trucks to merge more easily. Converging fork? Did I just invent a roadway term? 😲
