Wow, that sucks. I guess Canada is further ahead in that. Electric car charging is 20 minutes per 3 hours here. I can see why it would make a big difference if it's an hour for your chargers.
It could also be the software for your car isn't well optimized, they should ideally be having you stop around 25% battery and charging up to around 75% if you are trying to make the best time. The software should inject the stops as close as possible to that ideal if you tell it to prioritize speed.
But if the only chargers you have on your route are that slow, then I guess there isn't much you can do but hope companies don't stop funding the R and D and contsruction of more up to date ones.
