It is surprising that you would think accepting more payment methods is somehow worse than offering fewer.
Additional security vulnerabilities, additional costs to implement and support possibly blocking new better approaches, additional complexity...
If checks had not yet been invented, and someone came to Europeans saying, 'I have this new ultra-cool system of payment which involves trivially forged signatures on paper where the bank upon receiving it takes a photograph rather than store it on paper and where fraud may not be detected for days; also, you have to manually keep track of the balance and if you don't and you write a check that bounces you'll be fined by the bank and maybe also the person you wrote the check too; and did I mention that the security is so weak that people who want to distribute their checks far & wide like Don Knuth can't do it because their bank accounts will be raided? Pls pay me $$$ for my kicking invention kthnxbai', do you think they would greet him with open arms?
Yes checks have downsides, but they have upsides as well, which is why a substantial percentage of people prefer to receive them. You should read about this thing called "Revealed Preference." For example, more than a fifth of black and Hispanic Americans don't have checking accounts--usually because of bad experiences involving a overdraft fees. So being able to receive checks is a nice convenience for them.
Also with checks you avoid interchange fees, so there are advantages to merchants as well.
I strongly suspect that in Europe the number of &q...
Having read through all this material, my general feeling is: the near-term future (1 decade) for autonomous cars is not that great. What's been accomplished, legally speaking, is great but more limited than most people appreciate. And there are many serious problems with penetrating the elaborate ingrown rent-seeking tangle of law & politics & insurance. I expect the mid-future (+2 decades) to look more like autonomous cars completely taking over many odd niches and applications where the user can afford to ignore those issues (eg. on private land or in warehouses or factories), with highways and regular roads continuing to see many human drivers with some level of automated assistance. However, none of these problems seem fatal and all of them seem amenable to gradual accommodation and pressure, so I am now more confident that in the long run we will see autonomous cars become the norm and human driving ever more niche (and possibly lower-class). On none of these am I sure how to formulate a precise prediction, though, since I expect lots of boundary-crossing and tertium quids. We'll see.
0.1 Self-driving cars
The first success inaugurating the modern era can be considered the 2005 DARPA Grand Challenge where multiple vehicles completed the course. The first legislation of any kind addressing autonomous cars was Nevada’s 2011 approval. 5 states have passed legislation dealing with autonomous cars.
However, these laws are highly preliminary and all the analyses I can find agree that they punt on the real legal issues of liability; they permit relatively little.
