ED: Why this discrimination?

To ban intercity travel on buses alone, which disproportionately affects the poor, is discriminatory
While the government’s decision to impose suspensions on intercity travel as part of the nationwide lockdown is one which can be wholeheartedly supported, it seems that the lockdown itself is not one which is being wholeheartedly implemented.

The ban seems to mainly apply to buses traveling between cities, but not on private cars or airlines. Public transport within cities, though, can continue as per usual.
