If you design your car in a way that the basic functions (engine, breaks, steering, etc.) compete for the same resources your IM app uses, that's a problem with basic design, not with connectivity.

Yes, I agree. Problem is that cars are turning into pseudo entertainment centers on wheels. You can only put so much tech into a car until the costs of doing so becomes a burden. Then its just more cost cutting measures. Which might include having one on-board computer powering all of the systems.
