Do you assume that we will purchase self driving cars frequently enough that the infotainment will keep pace? Do you anticipate purchasing a personal train or fighter jet? Do the handlebars on a motorcycle count as a steering wheel?
Of course such vehicles will have infotainment. I've long been thinking about what sort of content would work best. Short, serialized content released on a weekday schedule would certainly be an opportunity. Perfect watercooler fodder.
As an employee you could get the ride in the car free, as a perk, iff you watch the educational material and pass a test on it. This would be assessed during the ride via onscreen multiple-choice questions; get less than 50% correct (or, turn it off) and you have to pay for the journey!
PS: I can see the argument for a highly limited system when they can distract the driver, but if I am effectively a passenger that's a non-issue.
If I'm the passenger, I should be able to tinker with the infotainment system as I like, without restriction (especially when my dad is the driver and I want to enable bluetooth audio to play music from my phone - my dad drives a newish Outback, great car from a driving perspective, crappy from the infotainment system perspective).
