Survey rewind: how much pain at the pump will it take to switch to EV? [update]

Gas prices have jumped sharply, with a gallon of premium reported at $7.19 in Chicago. That has renewed a debate about how high fuel costs need to climb before die-hard gas-car owners switch to an EV or hybrid. A reader survey earlier this year found that nearly half of respondents believe some drivers simply won't switch no matter the price, pointing to Europe, where gas already runs over $11 a gallon in some places and plenty of drivers still stick with gas.

For homeowners weighing the switch, the math isn't just about gas prices. One point raised is that if your current car is paid off and reliable, it may still be cheaper to keep driving it even as fuel costs rise, until it needs replacing. Another is that electricity rates matter too, and they've been rising in some areas, which changes the cost comparison between charging and fueling up.

The piece also highlights an advantage specific to homeowners: pairing solar panels with a home battery and an EV lets you generate your own "fuel," which can shield you from swings in both gas and electricity prices. One person quoted described this setup as locking in energy costs for decades rather than reacting to whatever gas costs on a given day. For anyone with rooftop solar or considering it, that combination is framed as a hedge against volatile pump prices rather than a direct response to any single price threshold.
