A terabyte of data every minute is a rather tall order to transmit via WiFi, even with 5G. Also, 60TB of data is one heck of stack of hard disks to put in the trunk (or boot), and driving for one hour is not all that uncommon. What is the data retention policy ?
So how is the car linked to the Azure server, and what is being sent/received ?
Also, when the learning phase is over, what kit is going to be left in the cars ?
