Turns out it’s exactly where anyone with a newer vehicle would think: directly in front of and near the vehicle.

I remember reading about someone that had created a workaround for this. She had exterior cameras and their images were projected onto the car's pillars, so that when you looked at a pillar you actually saw "through it", i.e. the exterior view it was hiding. I wish I could find the reference.

I hear the new Canyonero has 360 view cameras as an option.

Any chance the traditional blindspots have been metricized and included in regulatory testing so car makers only care about those and not safety in general?
