I hate these things. I'm driving around the suburbs of Melbourne in a 900kg hatchback carrying 3 kids and their schoolbags. I find myself constantly overtaking these things as it's the only means of seeing past them. I'm not even courteous about it anymore.
I don't tailgate, but I want to see what's happening up ahead. Positioning plays a large part in road safety. Maintaining a safe road position requires getting in front of visual obstructions.
I should also be able to go faster. Compared to a Ford Ranger doing 100km/h, I would need to be doing 147km/h in my car to leave the same sized dent in a collision.
No offense but your arguments are not rational. You don't need to "get in front of visual obstructions" if you're following at a safe distance. Speed is not limited simply because "faster means more damage", it's limited because faster speeds means you have less time to react.
Then follow at a safer distance. I'm sorry but this is driving school 101. We can complain about pickup trucks being hard to see past but it's not like you can see past buses, or delivery vans, or other large trucks. Aggressively passing a vehicle because you can't see past it it moronic.
You should always be leaving enough space between you and the vehicle in front of you to allow you to stop in case of an emergency. Even a convertible that you can see perfectly overtop of might have to stop unexpectedly and if you haven't left enough space you will rear end them.
If you don't feel safe following a vehicle you can't see past, it's probably because you're tailgaiting. Stop tailgaiting! And I know some of you are tailgaiting because it seems like 50% of drivers on highways tailgait.
Imagine thinking other drivers won't cut you off for attempting safe follow distance. The masses move in bumper-to-bumper pods and the only way to achieve safe following distance is to get out ahead of them, or luck into being already at the head of one of their pods.
Also, imagine thinking the only way to get and stay in front of these schmucks is to speed wrecklessly. I can pace a car in my rear-view and keep them at a safe distance even if they would rather not be. Control what you can control, or embrace the un-safe standard drone behavior, but if you evangelize the latter, you're going to get well-deserved pushback, and likely mocked.
In my experience, it's the large trucks that are speeding and overtaking dangerously, not to mention driving much faster than the conditions would dictate. A rear-wheel drive vehicle with nothing in the back on an icy road is a recipe for disaster, but I see it all the time.
