I am not quite sure how the transport works here (Australia) but it's most definitely not a random taxi. The hotels are paid for and organised by the government and are guarded to ensure no one goes in/leaves, so I assume the transport to the hotels is also tightly monitored and the safety of drivers is ensured. I believe China has similar procedures. Before the hotels we had self-quarantine and that actually caused an Uber driver to become infected when he drove a cruise ship passenger home.
