advocate this as a mass solution, because the law in PA is clear that you are not allowed to vote absentee unless you will actually be out of the area or unable to get to the polls that day.
This means many of the elderly may have a "legitimate" reason to vote absentee (difficulty of getting to the polls). But most of the non-elderly people who do not have a drivers license would not be legally permitted to vote absentee, because they would theoretically be able to get to the polls as usual.
Still, I agree it will be a good approach for many people.
Below is the relevant portion of the regulations on absentee voting in PA:

You may vote absentee in PA if you are:

An individual who, because of the elector's duties, occupation or business (including attendance of college in another coutny/state, leaves of absence for teaching, vacations and sabbatical leaves), expects on Election Day to be absent from his/her municipality of residence during the entire period the polls are open for voting and the spouse and dependents of such electors who are residing with or accompanying the elector and for that reason also expect to be absent from his/her municipality during the entire period the polls are open for voting (7 a.m. to 8 p.m.).

There are other categories of voters who may vote absentee (military, disabled, etc.) But you cannot vote absentee just because you prefer to do so.
