Many people buy cars based on capabilities that they never plan on fully exploring. We are seeing a trend with newer crossovers to be focused around outdoor lifestyles and that's probably why JLR felt the need to ensure the E Pace could handle light off roading. The I-Pace was put through nearly identical tests.
I think its far more simpler than that. They buy for styling and character which is influenced by capabilities they're not entirely aware of. Most people are scared to pop the hood and wouldn't know where to start.
