Your assumption is that only small EVs will go through these tunnels in the future. I think that assumption is flawed. Tesla announced it wants to make high-passenger-count commercial EVs (akin to vans and buses): https://www.tesla.com/ns_videos/Tesla-Master-Plan-Part-3.pdf https://www.tesla.com/ns_videos/Tesla-Master-Plan-Part-3.pdf EVs that carry 8, 12, or more passengers (perhaps by chaining the EVs) would significantly increase the efficiency and throughput of these tunnels. And then there's a big question mark on self-driving, which, if achieved, would significantly improve the economics.
