If you sell a ton of these cars, having employees controlling 2% of the time means your costs become enormous rather quickly. You would have to have a subscription business model for this to make any sense where the person buys the car and then has to keep paying monthly for self driving.
Cruise is aiming for a robotaxi market, not for consumer vehicles. In their business plan, they own and operate fleets. In that kind of model, itβs possible that they can get away with 4% human control. Another way to put that is that they would have one operator on duty for every 25 cars.
No-one credible is talking about selling self-driving cars to consumers for a long time. Taxi services make much more economic sense and are all-around more comfortable from a liability perspective as well.
