> But you can’t just walk away from a gasoline car when it’s filling. And gas stations aren’t very attractive destination to do much of anything.

That's probably a US (or maybe some other places) thing but you certainly can do that here in Estonia. I do it all the time - start the pumping and then go inside to the gas station to buy a drink or whatever. Especially with the in-app payment for gas it's great.

Never heard of anyone having an accident with it either...
