if we add up all the highway lanes in a city there will usually be maybe 20 - 30 lanes of 12 feet wide each or about 400 feet of highway width total in a city that is 20 miles wide. even without stacking we could easily quadruple the number of lanes.
throughput is a complete non issue. they are REMOVING lanes in the most congested roads to create traffic on purpose.
in NYC they cut the most congested road ( BQE ) right next to Brooklyn Bridge ( to Manhattan ) from 3 lanes to 2 ! they did this during lockdown when everybody stayed home and noted that accidents went down. then they said accidents went down not because everybody stayed home but because 2 lanes are safer than 3 somehow ... and made the change permanent.
these are the fuckroaches who tell you that we will never have enough throughput and that we can't build enough lanes. the people who thought 3 lanes was too many for a city of 20 million - that's who.
they also tell us that we have no space - yet the blocked off lane isn't used at all. it simply sits there blocked off.
their agenda is 100% transparent to anybody with eyes to see.
