Those are a lot of questions!

First, regarding vehicles, I think I'm okay with them, but I don't think they're necessary except in a few cases. For example, the addition of the Powerdizer in Fourze is pretty welcome and needed for me. Thus, I would say that the vehicles have to feel "necessary", not just tacked on.

I'm not, however, a fan of the CGI used for these vehicles. They're even more conspicuous than the Sentai mecha because Rider action is often up-close and in-your-face. I really wish Toei would improve on the CGI for all their shows.

I'm fine with Riders fighting giant monsters, it can be pretty epic if done right.
