Vehicular traffic should be banned from inner Cities.
In many ways I do agree. It can take longer by car to get somewhere then using the subway or biking, however many cities don't have the infrastructure or funds to really set up a mass transport for how many people it has. Ideally it would be great for people to bike or walk but not everyone can do that.
Walking seems to be viewed by today's snowflakes as something not even worth considering.
What is needed is for everyone to accept the findings of the world's most eminent scientists that earth is on the road to environmental disaster and to develop a sense of urgency and adopt the necessary measures which may avert this global catastrophe.
