Japanese automaker Nissan (NSANY) finds itself at a crossroads. Nissan was poised to participate in a megamerger with rival Honda (HMC), and it was a huge development when the talks were revealed late last year.

There's strife of the horizon as Nissan vehemently opposes Honda's suggestion of making the struggling carmaker its subsidiary.

Even if the merger is off, Nissan remains keen on working with Honda in areas such as electric vehicles and software defined vehicles.
