Something tells me people aren’t just coming up to the OP and commenting on the choice to go car light or car free.

More than likely the subject is broached by the OP as a question that solicits opinion. Once opinions have been asked for people that can see no reason for such a change in their life are unlikely to be supportive of the OPs change.

If the goal is to become car light just do it and don’t ask permission.

Once you open a alternative lifestyle to debate that is what you will get, debate.
