I think what they're actually worried about are shoddy drivers giving up the BSOD and tarnishing their brand in the process.

The number of items that a person can hold simultaneously in their working memory is known to be related to the ability to understand and solve complex problems.(See Working Memory Capacity)

It'd be silly to think that with the ability to keep more of the relevant details in working memory one wouldn't be much more likely to find a connection. To make a machine analogy, there is an exponential increase in possible configurations that can be represented and analyzed by adding another register. While the brain is not a computer and is really quite mysterious, I don't see how the benefits could be much different.
