I think the 6 minute timeout it could be a fallback mode in case the component sending the commands malfunctions and keeps spamming the same command in a loop over and over again. Granted, if this happens while driving you're likely to have an accident anyway, but if you don't, then waiting 6 minutes would allow you to reclaim your steering for the rest of the journey.
