5. Automotive - IoT - and embedded

Improved research, design, manufacturing, and marketing processes have also helped the automotive industry stay competitive. Even more importantly, advanced analytics has led to the development of self-driving car systems that include sensors such as camera and radar systems, GPS systems, inertial navigation systems, and more. Unfortunately, a lack of data science has made it impossible to keep track of tire wear, mileage, fuel efficiency, or driving patterns in light of the increasing complexity of automobiles and their ability to collect more data. So, expect self-driving cars without requiring a driver to communicate, collaborate, or navigate soon!
