Traffic and cars need a do-over. This became particularly apparent when bureaucracy got added to the game. Hybrid and electric car policies continue to be necessary after the electric cars trasition is complete or else electric car transition will back slide. Additionally, losing the direct environmental boosts from these will result in ecological disaster.
Point 1: no policy related to cars should produce a direct environmental benefit, instead it should reduce the environmental harm of cars.
Point 2: traffic congestion should carry a portion of the environmental damage from cars. Engines running at low load produce worse emissions than engines running as intended. Traffic congestion should also carry most of the inputs to respiratory disease and obesity.
Point 3: electric car transition should have a self sustaining input. I donāt if you could program this (Cliff, if you only answer one point here, please tell me if this one is possible to program), but this condition should input to itself. Low levels of electric car transition should decrease itself. At high levels it should increase itself. This would reflect the difficulty of a new technology breaking into an established market. On the flip side, if EVs have so thoroughly taken over that petrol tax is producing zero income, therefore the petrol stations have gone out of business, technology should not back slide if I end the subsidies for EVs.
That concludes my points on the environmental imact of cars, now for what causes people to drive
Point 4: āIf you build it they will comeā is a fallacy. In game, if I build more roads for the reduction to traffic congestion, then my citizens see a road and drive on it more because it exists causing even more congestion. Many people believe this is how real life works, typically people who hold this belief havenāt travelled much.
Point 5: Transit pressure. People donāt drive in congested city traffic just for the fun of it, they do so because they have somewhere to be. A good change was made with āimmigration pressureā being added to the game, we now need ātransit pressureā. The main input to transit pressure should be GDP, at least for now. Transit pressue would drive all forms of transportation, but individuals donāt have the capacity to personally schedule the bus or build a monorail. The only things an individual can do is purchase a ticket if mass transit exists, or drive a car. Therefore, car usage is what people should turn to IF the player has not provided any other means. The PC to increase road building should be much cheaper, and the benefits should come faster. This way ājust build more roadsā is the quick and dirty way to fix congestion, but doesnāt solve the most problems. Development of better transit infrastructure should have such slow inertia that there will usually be another election before it really provides benefit. This way the player who is uncertain of the next election is tempted to go for the quick solution of road building, much like the real world.
