If anything it’ll probably be less likely for majority of people to eat for example while riding one, specially if there’re fleets that are operated by a company. Think subway, you’re not allowed to eat or drink, yet currently people do eat and drink in their personal cars.

If self driving cars are individually owned then there may be a trend towards a different experience but that may come much later after we have self driving cars hitting the road, as the cost and risk to operate one makes it unfeasible for the manufacturers to sell them at scale to the general public instead of operating their own ridesharing fleets.
