As for online voting, at the moment, we know very well that the generation of elderly people is not really comfortable with the Internet and technological tools.
In addition, in some regions, such as my own, Internet access is not available everywhere. So you could not take that option and offer it to everyone. Seniors are very afraid of everything done on the Internet. They are never sure whether it is legal or secure. That generation will be changing. Today, people who are 50 or 60 are more comfortable with technology. At the moment, if that method were the norm, a lot of elderly people would not vote because they would not be comfortable enough using the tools.
In response to your first question, I must say that we would indeed like people to be able to vote in places other than community centres and schools because some people with reduced mobility cannot travel as easily as others. Even if parties call and offer to come and get them, they are still reluctant because they do not know them. They do not venture out with anyone. If they could vote where they live, it would be a lot easier for them.
