I hear ya on the visibility thing. I once test-drove a GM coupe called the Pontiac G6. It was similar to the Camaro in that it had enormous C-pillars that made it impossible to do an over-the-shoulder look. I remember saying to the salesman, “Wow, I’ve been in this car like 2 minutes and I already hate it just backing up out of this parking space.” Sales guy literally said, “Think about though. We’re on a dealer lot. How often do you really need to back up out of parking spaces in your regular driving?” Uh, all the time, a-hole.
But it varies, though, based on styling. BMWs typically have good rear visibility, even in coupes due to their bubble-like shape (other than maybe something like the i8),
As someone who drives only 4 door sedans and hates SUVs the current cars also suck for visibility. The high belt lines make for poor right rear side visibility. Just another reason to not buy a new car.
Recent Pick-Ups can have more than 6 cameras to help with low speed maneuvering.
