Why would the self-driving car vendor charge $20 if you ride by yourself or $5 if you share with one other person? They'd be getting less revenue for a longer, more time consuming trip due to the need to pick up and drop off the 2nd passenger.
I could see them charging something like $10 for one person and $7 each for 2 (which is close to actual Lyft pricing). That way they give a price break to the user, while they themselves also make more money, so they have an incentive to offer that pricing even if the trip takes longer, or they can't find a 2nd rider.
