Not to mention the asphalt roads we drive them on! Though that cost is shared by all drivers, it has to be accounted for somewhere.
Even if we have a 100% electric vehicle fleet, we'd still need oil to make roads and tires. Plus the 88g from the study. Since EVs are being sold as a way to "solve climate change", this is a big problem. Most people assume a transition to EVs would mean stopping oil. They are wrong.
