I would say that with wide availability of LTO batteries (practically unlimited cycle life), this is now obviously the case. If you run a small LiFePO4-graphite pack empty everyday, your battery costs are going to be horrible because that battery pack will be gone in a few years. Batteries need to get 2x cheaper and 2x more dense before gasoline unequivocally loses.

My parents leased an X5 40e which could go around 13 miles on the 9.2kWh battery, maybe 15 if you took it easy and went slow. An overnight charge from 110V was enough to fill it up. On a more efficient small sedan instead of a giant boxy behemoth, 25-30 miles of range would be easily achievable.
