I have noticed through my playthroughs that Car Usage itself influences the Environment, rather than the CO2 emissions that are also calculated. To me, this is nonsensical, and often leads to situations in my games where despite having 0 CO2 emissions, Car Usage is the driving factor (besides GDP (more of that later)) behind my worsening environment and my unsolvable respiratory disease crisis.
I suppose I can understand the argument of Car Usage itself making respiratory disease worse, as an asthmatic I well remembered the (albeit ignored) advice I received from doctors in my childhood to try to walk to school as it would strengthen my lungs, weakening the effects of the asthma. However, for this same reason, surely Bus Usage and Train Usage would effect it. Instead, it is the “polluter” of the commuting options, the Cars, which seems to imply the reason for the impact is on pollutant grounds rather than inactivity.
As such, I feel like we need to do the following:
a) Add Bus Usage and Rail Usage as impacts on Respiratory Disease contributors, but at a lesser level than Cars.
b) Remove Car Usage from the impacts and replace it with CO2 Emissions, in order to actually represent the problem of “Car Fumes” stated in the crisis description, which is solvable through having fume-less electric cars.
Take away the impact Cars have on the Environment, and replace it with CO2 Emissions. It always seemed weird that CO2 didn’t influence the Environment. This way, we can still measure the impact Cars have, but through the medium of their emissions, rather than by nature of being 4 wheeled chunks of metal. This makes it so it’s viable to do an electric-car focussed playthrough, instead of being forced, as I always am, to switch to a staunchly anti-motorist stance, banning travel all together, to fend off the crisis.
I can understand that there’s an argument that Electric Cars still impact the environment, as the energy has to come from the National Grid, which is often powered by coal or oil. However, we don’t simulate the pollution the National Grid produces, and if we did, we could still remove this problem through the usage of Clean Energy Subsidies, Microgeneration Generation Grants, Mandatory Microgeneration, Nuclear Fission, etc etc. There is no need for a direct link of Car Usage to Environment.
