Isn't it dangerous if the transaction signal queue can trigger the gas to overflow and become a fire? unless previously ordered with the application system in advance. if they don't use stable coins, many will be confused by the ever changing rates.

Well, we can actually implement some other optiins like putting up the funds in a card where we only need to tap it to pay amounts we need or else is to pay thr gasoline in a distant counter, as simple as qr scanning will do, becauss most of the time, we get tired especially if it is a public transportation and we're late, the driver needs to ciunt his money first for payment but with crypto, transactions will be faster.
Using QR code to is applicable. There is a system in my area where you use G-cash by just scanning the QR and you'll be able to pay it. It can be adopt by bitcoin too in terms that there is a specific wallet that both gasoline station and customer will be use.
