Not really. the "fact" that they could have easily made it a default option is a fact not an opinion.
it is quite literally a few lines of computer code. would likely take the programmer all of 30 minutes to add the code line in place.
well about 30 seconds to add the default option code and 29.5 minutes to add the UI infrastructure to make it user selectable.
not trying to be a dick but I do not recognize "agree to disagree" type solutions
Ok this will be the last that I will post on this. Since the OP started with the topic of B being default because of perception that it allows you to get more range. If, (as stated by the others in the post who want it, not me since I don't think it will give you better range) B gives a difference of range and that shows up in the EPA tests then it by my understanding of EPA rules it cannot be something that comes on by default when you turn the car on unless they use the B mode in the test to determine the number on the EPA sticker.
Unless you know a Nissan engineer who worked on the car and you want to share his contact or you want to go to the trouble of digging up all the EPA test rules and quoting them it is unfair to say that you know it is a fact that they could program the car like that.
Maybe it would be better to say that they should have designed the mechanicals of the shifter closer to the prius that has a different gate for B and D that the user can select on start up them selves, or a 2 sec hold feature that engages B.
I just kept posting to allow new people who read this to know that B does not give any magical range so don't start using it. Yes some people have learned to carve wood with a chainsaw but don't look at their carvings and think well a chainsaw is the best way to do that.
