@HayiWena would a "reasonable Engineer" "improve traffic conditions" by maintaining designs that yield a network which is clearly hostile to alternative means of transportation, given the decades-long-studied irrefutable fact of #InducedDemand? "in accordance with ... municipal regulations, standards and manuals" - but the MUTCD, at least, says explicitly that the guidance is no substitute for an Engineer's judgement. Certainly there is windshield bias of judge/lawmakers, but buck stops where?
