You're comparing size only. There are far more aspects of a car's design which determine practicality and market perception. Current market prices aside, the ID.3 is designed to be perceived as a cheaper car by dint of being a hatchback with lots of hard interior plastics. To be clear, I'm not criticising the ID.3, my next car is probably going to look more like the ID.3 than the Model 3. But nonetheless there's a market that's excited by the Tesla's blistering performance and driving dynamics, while there's another market which is more excited by the ID.3's practical and conservative construction.
