Better performance in the same way a laptop performs better than a microwave, or a mechanical device. People were fine with mechanical speedometers, but manufactures moved to microprocessors because of cost/features, and seem to be moving towards mainstream computers for the same reason. People don't need these features. A mechanical speedo would suffice, but they seem to want them. Along the same lines, people would be fine if the only car available were some kind of utilitarian hatch or station wagon, but people want cars with different attributes and manufactures offer and optimize for those attributes. Having in car entertainment can help to make longer refueling stops more pleasant, which arguably helps with adoption. But it's not a requirement. Tesla could have skipped it and lived with however many different sales, in the same way including it led to different sales.
