I don't have an EV but driving one is weird. I can't seem to get used to it but I have driven them a few times. So honestly, I think your friend should just go with whatever he is comfortable with. Hybrid or full EV, I don't think there is too much of a difference because the hybrid will be running on EV most of the time anyways.
Integrity is tough. I think that most people tend to have a price for most things. This could be money or actions. It depends on what people want and most of the time, the people in charge don't really care about us.
For him, this is probably true, for me it wouldn't be, as there is a distance thing. However, there is a difference in personal contentment. I know hi quite well and he would "feel" the choice he made either more positively or negatively depending.
Yep. Everyone has a price, and no one truly knows what theirs is, until conditions are met.
