"Decreased cost" will only be true as long as they still have to compete with human drivers. Once they manage to drive (hah) those out of the market, they'll start enshittifying and surcharging wherever they can.
"You're absolutely right to be upset. I should have notified you ahead of time that this section of the highway is closed and I cannot complete the trip you paid for." "Then exit the highway, dammit!" "Very well. The upgrade has been charged to your card." "The fuck you mean, upgrade?" "I'm sorry, I should have been clearer on this. You just purchased the Road Map modules for municipalities within 30 miles of our current location in order for me to consider alternate routes not involving the highway. Now please enjoy this entertainment while I select the optimal route." 90 seconds of ads pass "New route selected. Estimated arrival: three hours and fifty-three minutes. Overtime extensions have been charged preemptively."
