I assumed you would have time between exits on slower roads unless you're driving an hour on the freeway to visit a roadside stand or something.

I grew up in Ontario and I'm familiar with the area. It still seems like an absurd trip plan but you do you.

Though we're back to the fact that even in your worst case the most that can be said is it would be slightly more inconvenient given current charger network. In reality you'd problem just do a better job picking a base location or not choosing one given the distances if you were really worried.
