Flutterby™! : Karaoke apps in cars

There's a lesson here about making sure your car's entertainment system is fairly open and generic... BMW and VW are missing out in the Chinese market because their cars don't run karaoke apps

Customers in the world’s biggest auto market are demanding that sing-along apps such as Changba work in new vehicles. Local manufacturers XPeng Inc., Nio Inc. and BYD Co. are at the forefront of this trend, besting Western rivals by offering models with karaoke microphones. The push extends beyond music, with Chinese buyers expecting seamless access to features like in-car payment and social-media connectivity.
