It doesn't make sense to compare Tesla to other car companies that way. The others have much higher volumes to spread costs on and they have been doing this stuff for over 100 years. That means the basics of car manufacturing has already been developed. Tesla R&D isn't just about creating yet another model, but about creating the very first car model in that category that they have ever done. I think it would be very odd if they kept having equally high R&D when upgrading their models.
