I don't think there was any idea bashing. It was more a case of people speaking up for the manufacturers saying it is not their fault Slot cars don't demand as much consumer focus as smart phones.
Personally I have a protoytype onboard sound system I am testing. It would make no sense for me to ask Carerra to do this, because I believe as much as I think sound is important, that vast majority of people couldn't care much less about sound. So I continue forward on my own and at sometime I will share a post on how others can do it if they want. That is the way this is going to have to work its way ahead with such a small enthusiast base.
So please don't stop thinking of stuff we need. They may be someone out there with the talent and time to build it, but it isn't like to be any major manufacturer.
