You'll end up a) waiting longer for "uncommon" vehicles, b) paying more than for an L5 econobox stuffed with three other commuter. Minivans are being used in these trials because they can carry multiple people to different destinations. That's the only reason. Minivans suck. Imagine a boat owner. They need an F-150 with a trailer hitch, plus the wiring for the boat trailer's lights. So if they want to move their boat around, they need to wait 20 mins for something they can currently do right now without waiting, without dealing with network outages, with the ability to tow something heavy. Look at the sustained performance of a Tesla S at Nurbergring. Towing takes a lot of torque, and will kill a battery like a Tesla. Plus the car needs to be able to get a bit wet/muddy sometimes.
