This one is interisting, one of the advantages that can we got from vehicle free days is from economics sector, back in my country this policy become a huge market. Not only we can walked around the city, but also to try some local food even bought some of souvenir. but even this look like really helpfull, there is always an dissagreement from it. We do not know about other peolpe activity, some countries celebrate vehicle free days on weekends and in national road, and on the other hand people have activity such as work, or just have some plan. And this event will make their stuck or looking another way to arrive their destination, it will cost their times. However, from those plus and minus, we can approve that it will always had a bad side or good side, as long as we can riding the waves, i think it should be fine.
