Why use the cars most robo taxi operators are deploying when the average cab ride consists of 1.2-1.4 passenger? Sleeker vehicles are easier and cheaper to operate autonomously, don't pose the risk to other road users the way Uber's Volvo XC90 or Waymo's Chrysler Pacifica present. Unless a ride-hailer is more thinking in terms of shuttles, which I call semi-PT. Below: when a certain AV tech level is a given, how will vehicles dimensioned differently perform in comparison?… Six critera.

There are three ‘tastes’ to autonomous vehicles: 1. robo taxis 2. shuttles and 3. personal passenger vehicles in which AV tech is used as comfort feature. IMO, in their attempt to incorporate driverless as a comfort feature in cars that have grown obese (SUV trend), carmakers have ruined AV development. Cheers, Ralph
