Did anyone else notice the video makes an illegal lane change in the middle of the intersection @1:13? Or is that legal nowadays to do?

I like the concept of this design, but I think an aspect of St. Louis driving is going to ruin it: all of the idiots who end up gridlocking intersections because they were trying to enter a road on the tail end of a jam, blocking the intersection. With traditional intersections, these people would only interrupt drivers going the same direction. With this concept, since they are changing the direction of traffic flow, will now overflow into traffic going the opposite direction.

@TFv052 I was thinking the samething, I don't think the idea of switching sides would be safe. it may seem efficient, but looks more dangerous

Is it just me or is this road gonna be super confusing?

Problem is that Americans suck at *merging* in traffic and letting others merge with you...well....we suck even worse at that.

Columbia prepares for this at Stadium Blvd and I-70. Cars leaving I-70 will pass through spayers that will hose them in *KY* so they can squeeze through this narrow and over-developed section of roads.

We have a *round-a-bout* which doesn't go any place....would have been cheaper to build a 25 foot straight section of a street. So we are very skeptical of this great idea

@MeyerVW You're a troll and an idiot.

Actually, herr Notchie, the classical definition of "liberal" is one that is open to change, whereas a "conservative" is a person who prefers more traditional values. They're both good and necessary. And I'll be damned if this doesn't play into this new-fangled traffic scheme.

But we weren't really talking about that. We were just calling EightBitH3r0 a "Republican" because it sends him into a tizzy, and that's fun to watch on a slow day, eh?

LOL!!!!!

[notchback]

Damn liberals.

So no "thankyou" for all of the help I am providing you? How ungracious!
