 @christophmartin5381 I don't know about that. Most of trucks I see here in North America go well above 110km/h

@89bazoly lucky you. Here in Canada they used to go as fast as they wanted. Often I look at my rearview mirror there is a tractor trailer riding on my ass and I was already going 120km. They sometimes go 150km when there is no police. Only a few years ago they mandated putting speed limiters in the trucks to 110km. But occasionally you still still encounter illegally modified ones that go over that limit.

Heavier the vehicle is the less efficient it becomes for Bev. Also the majority of mileage is on highway speed worsening the efficiency even more

@chrisheath2637 the physics is simple. The heavier the vehicle the larger battery pack it needs which in turn increase it's weight. Not the same with fossil fuel vehicles, it doesn't have to increase gas tank nearly as much as battery weight in order to achieve the same range or load increase. That said emissions is still emission. Just comparing small ice car to big ice car, small ice car pollutes more. Got EVs definitely big heavier EVs pollutes more in terms of resources extractions required.
