My 2020 Camaro LT1 V8 POV Drive 

I haven't found much issues with the blindspots and for me I can see fine without much issue. I also have driven other performance orientated cars that had worse visibility and have also towed many trailers with trucks to where I only had my side mirrors which probably are the main reasons I don't consider the Camaro bad visibility for me personally. As far as backing up it has a backup camera and the indicator lines move with the steering wheel. I have heard on forums where owners that had issues with blindspots have adjusted too it in a short time period and have found mirror angles that work well for lane changing etc. EDIT: I don't have issues with backing up and I back it into my small garage after I drive each time without issues. I hope this helps answer your question.
