I think the center of this discussion is understanding the real life requirement on an EV towing a boat to the lake. If the base requirement is an A to B to A trip, you’ve shown that the EV is sufficient. However the robustness of how the EV satisfies the requirement is the true issue to me. Can the EV meet the requirement with a headwind? Can it complete the task after forgetting the life jackets and having to back track a bit? Can it meet it in the cold? Can it meet it with a less aerodynamic boat of the same weight?
I think the ICE vehicle allows more margin for the unknowns that real life brings. There in lies the crux of the functional EV vs ICE discussion for me. I don’t think most people will relinquish the margin afforded by ICE vehicles fully until the EVs demonstrates true parity with ICE in all regard. Right now, EVs are a bit too far into the “good idea fairy” territory for me to fully bite off. I think we’ll see families adopt an EV but still hold ICE capability for the foreseeable future.
