A-posts protect in a rollover situation - it's particularly difficult to make them slim if the windscreen is steeply raked to improve the drag coefficient, as they would have to withstand a bending load. And the standard required has been - quite reasonably - been raised in regulations. Rear windows become smaller because they are lighter, so reducing fuel consumption. And the devices in the middle of the bonnet are of course a hazard to pedestrians in a collision. So good reasons for the design changes, although with side effects.

From my own observations , I found the worst offender for forward visibility is a Renault Captur. Huge A pillars at the front which make the car feel claustrophobic to the driver and difficult to judge obstructions.

You'd think that with all the improvements in modern material science/metallurgy and scrutural engineering that vehicle structures would be getting less intrusive/more airy and not the opposite.

It appears that they are going the easy route for improved crash protection but (IMHO) significantly sacrificing visibility whilst jacking up prices by compensating with yet more sensor arrays/safety systems.

The problem with such electronic safety systems is that they can fail just when you need them, whereas at least a car with decent all-around visibility etc will make accident avoidance/obstruction avoidance/parking relatively straight forward.

That and making car ownership a LOT cheaper.
