Overwhelming majority prefers shit[0] - people pick from what is made available to them, not from what could possibly exist, and they don't have direct say whether or when what's available changes.

These cashless solutions are just another thing[1] being pushed from top down; the passengers only notice when they suddenly find themselves unable to buy a ticket for coins, but by that point, the decision has long been made, so people only get to whine and complain, or otherwise express opinions that are not actually listened to by anyone with power to change things.

This is not saying that all those solutions are bad or inferior. Just that nobody is actually checking with people whether they want it or not; technology is deployed as fait accompli, and regular people just find ways to cope.

[1] - Like most technology, really, both software and hardware.
