I'm a massive fan of this wide-angle side mirror manufacturer called Suma Performance. They make some quality sideview mirrors. I already bought several pairs from them for my Tesla Model 3 and Rav4 Prime and they're all great. So I'm thinking of getting a CX-50 PHEV once it comes out but Suma currently don't have the mirrors. I emailed them to inquire and they told me that they could probably start producing mirrors for the CX-50 if they could garner enough interest from people (at least 20 inquiries). So if you guys are interested, please email them at support@sumaperformance.com. Their mirrors come in several versions (some have BSM and built-in indicator arrows). Here are the links to their mirrors so you guys can check out the quality for yourself:
