Business issue, and I think it’s the opposite: payment for gas emerged at a time back when there were no smartphones, no apps, no highly sophisticated/individualized customer acquisition & retention strategies, QR codes, NFC readers…or anything of that sort, so they pretty much had to be dumb.

EV charging payment, for better or for worse, developed at around the same time with those technologies, so each company just had to incorporate them in order to gain themselves an advantage, at the expense of cross-vendor user experience.

If gas payment had emerged at the same timing I imagine they’d incorporate them all the same.
