Would it make sense for ENCTS (I'm mostly thinking of the Senior version, maybe not the Disability version) to be suspended for the duration of the National Emergency?
Most who hold ENCTS are being advised against travelling in any case, and having to pay fares would dissuade holders from making unnecessary journeys. Yes of course they still need to eat as does everyone else, but there are rather few who really can't afford to pay for one trip a week to the supermarket. In any case, the supermarket cafe will probably be closed, so what they lose on the bus fare they get back by not having a cup of tea and a bun.
The advantages are two. From one end, it would put people off making journeys they don't need to be making. From the other end, the fares income just might help an operator to stay afloat. The downside is possible political fall-out, but party politics is mostly on hold for the time being, and the Senior population would probably actually understand the thinking better than the working age population.
