@Gasaraki To be fair, older cars - especially 90s or earlier - had much better visibility than modern cars high beltlines, thick pillars, and limited rear glass area. Model 3 is far from the worst in those regards, I think it's pretty good by modern standards, but still nothing like the visibility you'd get in most 80s-90s sedans.
The desire for blind spot warnings, overhead parking view, etc seems reasonably justified to me these days. I'm okay without, at least in the Model 3, but I certainly get why they're popular.
