Entertainment/connectivity systems in cars are either poorly designed, proprietary/incompatible, or both.

Most any data-driven desktop app can be rebuilt for the web, but the same can't be said the same for apps that depend on local resources outside of a browser's limited environment. Could you ever imagine pro video editing (i.e. Adobe Premiere / After Effects) 100% within Chrome?

This has happened at least four times in the last year or so in Atlanta.
