One thing I was taught as someone authorised to drive Police vehicles, and as an ex-motorcyclist is the 'lifesaver' turn before changing lanes etc. It's too easy to miss something in blind spots, and it does surprise how many normal cars have such large ones or even how poor the rear visibility is. The rear windscreens in some modern cars are incredibly narrow vertically.

I've spec'd my new E71 40D with the all round camera system for parking as I know my wife will struggle otherwise coz she's such a wee lassie.

I'll miss the moving load floor I have in the E53 too which makes getting heavy items in and out of the trunk so much easier. That rear bumper area concerns me as well, so I have also ordered a protector to go over it otherwise I can see it all ending in tears with a scratch (or worse).
