Some drivers say they'd like about 5 ft of diesel engine in front of them (not under) if they're about to rear end another rig.

This isn't really true and they are certainly no worse than most conventionals that are popular in the US. The biggest reason was change in regulations followed by personal preference of the truck drivers themselves. Cab over trucks have the advantage in overall length and turning radius which is why they are pretty much they only type that exists outside of the US. US truck drivers that are far more frequently using their trucks as a home on the road certainly don't like the idea of tipping the cab for engine maintenance and having their belongings spilled forward.

I got stuck in a convoy of them on 4/14 on I-57/US-60 in southeast MO. It was pretty damn cool.

Dad ran a trucking company for 30 years. Had an all cab over fleet and then phased them out over time. Fuel efficiency was a large factor, but the safety factor was prime. Over the years, he had a few drivers succumb in crashes in a cabover that would have likely survived in the conventional truck of today.

You're telling me that this
has the same aerodynamics as this?
I gotta hear this one.

What ever happened to these trucks? I saw so many back in the 70s. Never see them on the interstate anymore.
I went what felt like 20 years without seeing one on the road but they've seemed to have made a bit of a comeback with the vintage truck crowd, I've been seeing more and more of them on the interstates lately. To the point where my wife and I will be mid-conversation on the highway and she gets pissed with I cut her off and yell "CABOVER!" and point one out
All of our drivers all drive relatively new cushy trucks that ride like Cadillacs, all automatics, etc. So I always tip my cap to the guys still burning down the roads in a fixed up old cabover or old spring ride Pete.

Try unsafe in a crash. Drivers had little chance of not getting pitched out the front windshield or crushed.
In Europe rigs are designed slightly different. Because the city streets they have to navigate are much tighter. I got that from Angelica Larson’s YouTube vids.

I think length Laws in the 70's also had something to do with it. I remember reading something about that when I was wondering about this a while back.

I didn't mean gross weight. I seem to remember something about how the axles weighed out that made them very sensitive to popping for a heavy axle. I might be mistaken though.
Not true if some of the load was carried forward of the fifth wheel (piling cantilevered over the cab for example).
