Automakers don't advertise EVs at the same rate as ICE

We're in a cheap gas cycle so a dollar spent advertising a truck or SUV will result in a higher ROI than a dollar spent advertising an EV. We're still in an early adopter phase, and those folks will seek out the information on their own, little need to advertise to them, as they know more about the EVs than the salesmen selling to them. To reach a tipping point we'd need expensive gas and a built-out infrastructure of fast-charging stations, then you'll see more people buying EVs and more mfrs advertising to them.
