This sounds like you feel persecuted by truck drivers.
I’m not sure the observation about bed space is really true, except maybe insofar as modern safety regulations require more empty crumple space in the front of the car.
Also, to preempt a repeat, last time there was a thread on HN about saving pedestrians by banning pickup trucks, I ran the numbers and a very optimistic estimate for number of pedestrian lives saved by replacing every single pickup with a commuter car was like 200 people per year.
This is a worry factor for people with kids, walking a dog etc., because while the pickup driver may well notice people of adult height, anything below shoulder level is effectively invisible in close-up situations. Most unpleasant close encounters don't come from a speeding vehicle but going in a straight line, but drivers turning right on red or at a stop sign and focused on traffic coming to their left, while ignoring the existence of people trying to cross the street to their right (and sometimes to their left too, because they're gazing into the middle distance and literally overlooking people nearby even though the pedestrians have the right of way).
200 pedestrian lives a year seems like a lot to me, even 100 seems like an excess loss. If you factor in cyclists (though many cyclists are their own worst enemies) I think the number might swell.
Not if you do a population-normalized utilitarian comparison. 200 people is vanishingly small. There are a million other things to focus on first.
