Why should the government mandate something like that? Why don't you just give feedback to the businesses that they should make these changes and if you and enough other people feel the same way, they probably will. I understand government intervention in cases of dark patterns that harm consumers (e.g. the recent Intuit settlement in the U.S.) and to protect certain groups that are likely to be harmed or neglected (e.g. the handicapped, blind, etc.) but I'm not sure I understand the need for government to intervene in a case like this where it is a business choice and the consumer while annoyed is not really harmed and there is no monopoly (as far as I remember in Estonia when I lived there a few years ago it was quite easy to hail a normal cab anywhere and was the same when I travelled the Baltics), and personally I get very nervous when the government starts regulating very specific things.

this will never happen.

outside of the imperial centers, "big tech" have already reached into governments.

for example, latin america governments make it very difficult to schedule a dmv visit without a cellphone number AND a meta/facebook's whatsApp account. While all public universities accepted a free google meet account for covid time remote classes, and now got a surprise multimillion bill to access material uploaded to the system after the original offer period.

things are already way past the point of no return.

while rich engineers are busy fiddling with websites to solver their own problems (could your immediate family have hailed that ride when in a similar situation?) companies have already encroached themselves in the very foundation of the institutions that could solve this via public policy.
