Remote diagnosis is only one potential application, but you have to distinguish between the internal network and external communications. Remote diagnosis is usually only allowed by certain authenticated and authorized trustworthy parties, e.g., the manufacturer. As already pointed out, we will get a lot of services that depend on the Internet. However, these should not endanger the safety of the car. >> It just needs to tell the dashboard its current read-out.

IMHO unexpected connectivity of internal devices with the Internet is a safety and security nightmare. You definitely don't want that. However, some manufacturers already consider open programming platforms and an app-based model for some parts of the car, e.g., installing additional apps on the head unit. Even if they have only restricted access and are treated as untrusted, I think that it will not take long until we will see the first exploits on such a platform...
