There are things about the P1000 that were not very well thought out. But there are things about it that are unique to the industry and I believe that Honda will get the problem areas ironed out. I miss having the ability to shift gears with my Defender. The Pioneer is much more interesting to drive offroad, the Defender is pretty boring.
Unfortunately, Honda is a generation to a generation and a half behind some of the other makers right now and they are having to play catch up. This is related to their human centered engineering. Had this machine come out 5-7 years ago, it would have been a dominating force in the market. I am not sure why they didn't look at what causes some of the other makers to stand out from the pack. For whatever reason, Honda didn't look at it a system including ergonomics/ease of use/OEM accessories/integrated aftermarket. Unfortunately a lot of their accessories seem to have been added after the fact rather than looking at it holistically and looking at it how people will likely be using it.
Hopefully they will take a look at that and do some more varied testing in the future. I kind of get the impression that the test engineers at Honda tested it based on the limitations in the manual rather than looking at how people were likely to use it in the field. The water ingesting is a prime example. If you follow the guidelines in the manual, you will be fine. But who doesn't like to splash through puddles?!?! I do it in my Corolla for goodness sakes!
Not testing that was a major oversight that has thankfully been corrected.
All that being said, right now, if you are in the market for something that allows you to seat 5 without being a limo and/or want to have fun shifting in manual and still have a functional bed, the P1000 controls that niche.
