I could see some sort of Virtual or Augmented reality/feel like you are on board driving idea being an interesting but rather expensive blip of fun for some (like the Railscope trains in the past I suppose) as the customer would have to have a VR headset that was compatible with the system. I am somewhat surprised Lionel hasn't brought out some sort of augmented reality app stuff like some video games I think have done so that kids could see themselves board/deboard trains or walk thru the towns. Maybe they have and I missed it.
I personally would find the above interesting enough to try at a show or a friends house but not buy for myself. Toy trains for me are one of the ways to escape all the excessive virtual/digital/screen time most of us have to deal with to live/make money these days. I don't even like the idea of using my phone for a remote. Give me physical buttons, dials etc. I don't care if it costs a bit extra.
