Are there any behavioral economists on here? Isn't there a well-proven positive (meaning unstable) feedback loop between the increased supply of roads and the demand for them? Is there any way to introduce an effective negative (stabilizing) feedback loop into the system? Congestion pricing is an attempt to do that. How about introducing some kind of net metering into the system? Not only could people who use the road at peak times be charged a toll, but people who travel off-peak could get a credit. It should be possible for somebody who has an off-peak commute to actually earn a bit of money. Yes, I'm proposing the transponder-age version of the toll-booth person handing money to the driver. With respect to Mr. Musk, his tunnelling proposal is nuts: on many things he's good, not this. We did some tunnels in Boston in the 1990s and early 2000s. Caissons! Flooding! Cooling systems to freeze the mud so the buildings near the project don't fall down! Ventilation systems! Rats flushed out by the tunneling projects! Buried utility lines! In LA, several layers of underground storm drains! Cost overruns!
