Transfer rates of pumping gasoline are actually solved. The amount of voltage and amperage in the cables is terrifying, but it does work and it's in production now.
Energy density of gasoline (30% usable) is about 4 kWh/kg, and current batteries are about 0.25 kWh/kg. 0.5 is in the lab, 1 is probably attainable this decade. However, nobody outside of aviation really cares.
The BIG convenience of gasoline is you can carry it in a jerrycan. But again, the places where this is really important are very niche.
EVs don't have to beat ICEs on every metric, they just have to win at enough to be a better deal. A horse can use grass as fuel, and grass grows everywhere - yet cars still replaced horses.

The big downside of gasoline is that it has to be drilled out of the earth and produced in a refinery. Electricity can be produced almost everywhere with very little effort. Sure, the technological development ran differently (it was easier to transport fuel somewhere than to use electricity - many alpine huts had/have gas lighting for that reason), but today it is entirely possible to have off-grid electricity - not in a city and not for industrial purposes.
