    Traffic jams don’t go 40mph. They go up to 15mph and then back down to close to zero and back up to 15mph. That’s absolutely horrible for emissions.

      Again, hybrid cars are actually more efficient in that kind of traffic than at 40+ mph, and those sorts of traffic waves are usually caused by bad drivers not knowing how to react to road congestion.

      But sure, if people are regularly driving in stop and go traffic in a fully gas car, then I guess the pollution is worse than 40 mph. Adding new lanes would massively increase pollution due to the induced demand. There are more effective and cheaper ways to reduce traffic and pollution than to double the capacity of the road.

        LOL, you ninja edited your post to add that part about start-stop and then acted like it’s my fault for not seeing it.
