I agree with the ideas that are exposed, but at the same time I have to admit that it could be very difficult, because of the rythms and the needs of our everyday life.
First of all, reducing private vehicles can reduce air pollution and the use of energy. It was demonstrated by the pandemic period: all people were forced to stay at home, so the use of vehicles decreased. As a consequence, skyes were cleaner and the quality of air was better.
On the other hand, nowadays people think that private vehicles are more comfortable for their occupations (going to work, taking kids to school, attending courses): sometimes public transports are late or too full, provoking stress and frustration. However, also traffic on the road is very stressful and noisy: the solution could be to improve the public services, convincing people to abandon cars. Sometimes buying a month-ticket or a year-ticket for public services might be less expensive than the cost for the fuel that cars need. Some organizations (schools, universities, jobs) also offer the opportunity to get back part of the money for public transports.
Medicine and fitness experts say that avoiding cars and other motor vehicles is an advantage for health: going to work or to school on foot or by bycicle increases physical performances and reduces risks linked to the cardiovascular system, and it is also a benefit for bones and muscles. Sometimes, nevertheless, it is difficult because of – for example – bad weather.
Finally, I think reducing cars and encouraging other forms of transport is an advantage as regards a lot of aspects, but sometimes our needs don’t allow it.
