Using Crypto at Gas Stations

[Trader_Rob]

i guess, it's already planned by people there. but the fact, its still hard to be realized.
many many problem to make it true, lets say we choose btc as a payment,since btc is the most crypto coin recognize in this world.
but we know exactly btc is very very slow, or we can choose ETH as a payment,since it's more faster than bitcoin,but the fact ETH have a high fluctuaction, maybe the price will not be right.
of course there will be parties who are disadvantaged because of that.
its just on payment problem, another problem such as regulation, partnership, etc, its hard

Isn't it going to be problematic if we use it as payment on goods like one provided by gas stations? Since transaction process is very slow, isn't that only going to cause more inconvenience rather than convenience?
