      Using a cellular connection for that would be very slow, laggy and unreliable. It would also use a ton of data, which someone would have to pay for.

      A number of reasons:

      • uses a lot of data (car data plans are often pretty low)
      • relatively slow compared to 5GHz
      • coverage, you ideally want your navigation and music to keep playing even if you go out of range
