The Mahindra XEV 9e has been generating buzz thanks to a party trick that lets the car do a choreographed dance routine, using its doors, trunk and side mirrors in sync. This feature has certainly attracted attention, and made waves on social media, but there's a discussion as to whether it actually provides any practical value, or if it's merely a marketing ploy. But some say it's a great way to showcase the car's technology, and to make people feel like they have a connection to their car, while others think it's a waste of engineering time that could have been spent on something more important. This feature sparks a discussion around how modern car design should strike a balance between innovation, entertainment and practicality, and particularly in the hotly contested electric vehicle market, where manufacturers are always on the lookout for something to differentiate themselves.
